Why does an aquarium without algae with fish turn green?

Plaque on glass: symptoms and causes

The development of green plaque in the aquarium is quite common among aquarists. Most often, this phenomenon is associated with improper care of the tank and a violation of the biological balance of the aqua system, as a result of which algae develop in the tank, creating a dirty green film on the glass of the aquarium:

  • Protococcus is a unicellular alga that forms a greenish film in the form of a spot or strip on the glass of the reservoir. Easily removed mechanically.
  • Xenococcus. manifests itself in the form of rounded spots on the walls, it is difficult to remove and “grows” into the glass.
  • Diatoms are the reason why rocks, decorations and even plants turn green.

It is important to note that Protococcus is present in every reservoir and is an integral part of biobalance. However, the algae is active due to the following factors:

  • Increased accumulation of phosphorus in the aquatic environment, exceeding 0.8 g / l.
  • Maintaining long-term temperature conditions above 27C.
  • Increased salt concentration in the reservoir.

How to get rid of green plaque in an aquarium

Before you know how to remove green plaque to the end, you should determine the cause of the development of algae, and eliminate it, otherwise the struggle will be meaningless. After the adverse factor has been eliminated, the following tools need to be prepared to get rid of plaque:

  • A scraper with a blade. needed to clean glass.
  • Old bucket or basin with a capacity of more than 10 liters.
  • Water to replace the liquid in the aquarium.
  • Siphon pump.
  • Baking soda / wine vinegar to remove dirt and bacteria.
  • Bleach solution 10%.

How to clean your aquarium and get rid of green plaque:

  • First, you need to remove the greens on the walls of the aquarium, after settling the fish in a separate reservoir, and using a scraper with a blade. In this case, the water is not drained from the reservoir. For convenience, it is better to use a magnetic scraper.
  • Dirty water is pumped out of the aquarium using a pump: one hose is immersed in a tank, the second in an old bucket.
  • After draining the water, they begin to clean the internal elements. Decorations and decorations are taken out of the container and set aside. they should be dealt with later. After that, the pump is passed over the stones, pulling out dirt and algae, and over the ground. If sand or gravel is used as a substrate, the soil is loosened by hand and carried out with a hose at a distance of 2.5 cm from the bottom. This prevents the substrate from being drawn into the hose.
  • The removed jewelry and decorative elements are cleaned of plaque manually. If the level of contamination is high, then bleach is used. the elements are immersed in the solution for 15-20 minutes, and then scalded with boiling water.
  • Pre-settled clean water is poured into the washed tank, and the indicators are measured: temperature, hardness, acidity. If the parameters are normal, you should wait a couple of hours for the particles in the water to settle to the bottom, and the liquid becomes transparent.
  • The last step is to clean the aquarium from the outside, using baking soda or wine vinegar as detergents. To clean, moisten a clean cloth or sponge with the agent and gently wipe the surfaces of the tank and devices.

Signs and symptoms

Signs that an aquarist urgently needs to clean up and fight harmful algae include:

  • Loss of water clarity. the liquid becomes dirty green or brown.
  • Decorative elements, pebbles, driftwood and plants are covered with a thin film of marsh color, which can be seen even on the ground.
  • Large greenish spots are created on the glass of the tank. It should be noted that tiny specks on the walls are considered normal, but together with the above symptoms are already cause for concern.

All known causes of green plaque on the walls of the aquarium

A bright and picturesque aquarium is a wonderful element of the interior and the pride of any aquarist. But sometimes the impression is disfigured by a greenish coating on the walls of the aquarium, which gives the tank an unkempt and unkempt appearance. The reason that the walls of the aquarium turn green is the reproduction of harmful tiny algae. Newcomers to the aquarium hobby are often confused about what to do with a nuisance and how to clean the pond, as even after harvesting, green plaque reappears in the aquarium. To return the artificial reservoir to its previous appearance, you should find out why greenery appears on the walls of the aquarium.

The reasons for the formation of plaque

Experienced aquarists, based on observation and studying the question of how to get rid of greenery in an aquarium, have found the following reasons:

  • Incorrect location of the tank. if direct sunlight falls on the tank with fish, then this threatens with many problems, including the formation of green plaque on the walls of the aquarium.
  • Increased water temperature. when the thermometer exceeds 27C, a favorable environment for the development of harmful algae is created in the tank.
  • A large amount of waste. uncleaned food and pet waste leads to contamination of the container, rotting and a greenish film.
  • The lack of a filter in the tank is one of the reasons why stones, glass and decorations are covered with a dirty green film.

Preventive measures

To prevent the green bloom on the walls of the aquarium from reappearing, preventive measures should be taken regularly. For this:

  • Change the fluid in the reservoir regularly.
  • Check lighting power, water temperature and daylight hours.
  • Live vegetation is planted in the aquarium: the more underwater flowers in the tank, the lower the chance of plaque formation.
  • Algae-eating fish are inhabited in the reservoir: catfish, platies, labeo, and Amano shrimps.
  • The aquarium is regularly looked after: the soil is siphoned, food remains are removed and the glass is washed.

Green bloom in an artificial reservoir is an annoying thing, but not fatal. You can eliminate the dirty green film on glass using detergents and systematically taking preventive measures. By following the instructions and advice of experienced aquarists, every beginner will be able to achieve stunning results.

Solve it your self Algae Problem (Easy fix no money spent)

Preventing the recurrence of the problem

To do this, simply follow the following guidelines:

  • Regular maintenance of the aquarium. water change, soil siphon, filter maintenance.
  • Use only high quality feed.
  • Use glut (glutaraldehyde) at a prophylactic dosage.
  • Do not overfeed the inhabitants.
  • Ensure healthy growth of higher plants. fertilize, normalize lighting.
  • Don’t create overpopulation.
  • Always have the means to combat green water at the ready.
  • In the summer, it is better to use bottled water or osmotic water for changes, but not from the tap.

What to do and how to deal with it?

Aquarists know many folk methods that will help get rid of this scourge, but in especially advanced cases, you cannot do without the use of chemicals.

An overabundance of organic matter

An overabundance of organic components is the main reason for green water, it is just that organics always appear in different ways.

Most often, organic waste (fish feces, dead plant parts, uncleaned corpses of inhabitants) accumulate on the ground and begin to rot. Therefore, they need to be removed in time.

What to do:

  • Make changes little by little every other day, while siphoning the soil.
  • Remove all dead leaves and make sure that there are no inhabitants’ corpses.
  • Rinse the filter.
  • Increase aeration.

Finding out why the water in the aquarium turns green and what to do about it?

Many aquarists find that sometimes the water in an aquarium starts to turn green.

This happens for various reasons, but it leads to one consequence. a beautiful aquarium in a matter of days becomes like a swamp, and because of the green water it is impossible to see anything in it.

Plants do not have enough light, they begin to die, rot, which further exacerbate the situation. Therefore, green water in an aquarium is a real problem that needs to be urgently addressed.

Bad light

In too low light, plants cannot fully absorb nutrients, they begin to wither, and some plants die off and rot.

This promotes an increase in the level of nitrates, which are not consumed by higher vegetation, but actively contribute to the reproduction of algae, which gives the water a green tint.

Enhanced lighting speeds up the consumption of nutrients, and if they are not added in the form of fertilizers and the water is not enriched with carbon dioxide, then the plants eat up available nitrates and phosphates very quickly and begin to starve.

This is what algae use, because their development requires a minimum amount of nitrogenous compounds.

How to fight:

  • Darken the aquarium for a few days.
  • Set up lighting equipment.
  • If the lighting is too strong, then after the treatment start applying fertilizers and CO2.

Poor quality feed

It is not uncommon for the water to turn green due to poor quality feed, especially if the aquarist has a habit of overfeeding his pets. Uneaten food begins to rot, decompose and release into the water many chemical elements that provoke the appearance of algae.

Ways to fight:

  • Use only high-quality dry food from well-known manufacturers.
  • Refuse to use live or frozen food.
  • Do not overfeed the fish.

This often happens when feeding with allegedly cheap “vegetable feed”. green flakes.

Chemical methods

The use of chemicals is guaranteed to give results, but also undermine the biological balance in the aquarium.

It is worth using chemistry only after all alternative methods have been tried and proved to be ineffective:

  • Bicillin. 5. Broad Spectra antibiotic destroys algae in one day. But in addition to algae, all beneficial bacteria die, so an outbreak of ammonia / ammonium, nitrite is a matter of time.
  • Sidex and its analogues. Glutaraldehyde, known to any aquarist, is used in an increased dosage.

It is also effective, but has a number of consequences: it burns plant leaves, provokes pH jumps, has a toxic effect on aquarium shrimp and can kill some fish.

Regular addition of glutaraldehyde in small doses will be an excellent prevention of green water in the aquarium.

  • Hydrogen peroxide. The most common 3% pharmacy peroxide in large dosages is capable of oxidizing all algae in a short time and making the water transparent, while some plant species absolutely cannot tolerate the introduction of peroxide, and fish can get oxygen poisoning.
  • Why is this problem dangerous??

    By itself, green water is not dangerous for fish, but the causes of its occurrence can cause irreparable harm.

    In addition, due to the lack of lighting, the photosynthesis process slows down in plants, they do not emit oxygen, which is so important for the respiration of fish, shrimps and even beneficial bacteria.

    Therefore, it is so important to apply enhanced aeration during this period.

    The aquarium turns green. What to do?

    Green water in an aquarium is a constant headache for many aquarists. Especially often newcomers to this business or people who have ceased to monitor the condition of the aquarium and rarely change the water encounter this problem. In addition, there are many more factors that make the aquarium green. Land of the Soviets will tell you how to prevent water discoloration.

    The water in the aquarium turns green due to the rapid growth of algae. The word algae is not meant to mean the various plants of a higher order that you plant in the ground or leave to grow on the surface of the water. Algae are lower plants that we cannot see with the naked eye. It is they who are to blame for the fact that your aquarium turns green.

    How to prevent algae growth and get rid of green water? After all, it is impossible to completely sanitize all the inhabitants of the aquarium and equipment. And such measures are sometimes not needed at all. After all, the aquarium will turn green due to a number of other reasons. First you need to talk about lighting. Choose the right aquarium lighting spectrum. To do this, do not place the aquarium where direct sunlight will fall on it. The minimum distance from the rays should be 1.5 m. Most often, artificial lamps are used to illuminate the aquarium. Such light in the aquarium does not prevent the plants from developing properly, and the fish feel great. Watch the intensity of the light. In too bright light, fish become lethargic, and algae begin to develop too quickly.

    The aquarium also turns green for another reason, directly related to lighting. the wrong light regime. In winter, the aquarium lighting should last no more than 8-10 hours a day. In summer, this time can be increased to 12 hours a day.

    Sometimes, even with the right lighting, the water still turns green. The active reproduction of algae can be affected by water pollution by feed. Fish do not always eat all the food, it starts to accumulate at the bottom and pollute the water. In dirty water, chemical and biological processes are disturbed, which leads to the fact that the aquarium turns green. Therefore, try not to feed the fish too much food. Ideally, the fish should eat all the food in 10-15 minutes.

    The soil may contain various food residues and waste products of fish. Of course, good water filtration will help you deal with this problem to some extent. But in any case, good and timely soil cleaning will be required.

    In a green aquarium, you can put fish, snails or shrimps, which happily feed on the algae remaining on the walls and stones of the aquarium. Some fish, especially if kept from hand to mouth, are ready to pluck unsightly algae from rocks and walls of the aquarium all day long. Therefore, we advise you to get a platy, mollies or catfish. But a couple of fish will not be able to fully cope with this problem. Therefore, you will also have to apply other measures to eliminate algae in the aquarium.

    You can also do with improvised means to prevent water bloom. After all, the aquarium turns green due to the excessive amount of algae, which should be disposed of. Therefore, we suggest that you use this remedy: dilute streptomycin powder in a small amount of boiled water. Take 3 mg of powder per liter of water in the aquarium.

    Natural method of cleansing

    It is possible to eliminate the green tinge of water by natural methods, restoring the balance of the aquatic environment. The first way is to place algae-eating abodes in the aquarium. These can be freshwater shrimps, daphnia crustaceans, platies, catfish, snails or turtle. But when adding such “neighbors” to the fish, take into account the dietary habits of the latter so that they do not eat the new inhabitants at once.

    The second method is the use of plants that are characterized by accelerated growth and absorb excess nitrogen (it is this that is the component that triggers the water flowering processes). You can plant hornwort, pemphigus in the aquarium soil. But before planting, it is recommended to remove humus from the bottom and replace half of the water.

    Also, for cleansing in a natural way, you can create conditions in the aquarium under which green euglena will not be able to multiply at a rapid pace and will begin to die. To do this, lower the water temperature to the minimum acceptable values ​​and make the lighting moderate if it is excessive.

    Where to put the fish during cleaning?

    If the water turns green very quickly, and you decide to purify it, then the fish need to be removed from the aquarium using a landing net. Carefully remove all the inhabitants and transfer them to another clean container filled with suitable water having approximately the same composition as the previous one (outside the flowering period).

    If the greening is significant, then the water can be completely renewed. After replacing it, change the soil as well, since it is also probably infected, and it will be extremely difficult to clean it. It is advisable to immediately treat the new substrate from parasites in order to avoid unpleasant consequences. All plants are also transferred to temporary containers, in which methylene blue is added in accordance with the instructions.

    Decorations and decorative items that were in the aquarium should be sterilized or boiled over. Thoroughly wash the container itself with hot water, treat with soda and leave for a day, and then wash again. After such actions, you can place soil with plants in the aquarium, pour water and start the fish.

    why the water in the aquarium is green and how to clean it?

    Chemical cleansing

    If the aquarium blooms without algae and plants, then chemical agents can be used to normalize the composition and shade of the water:

    • Try adding granular activated carbon to the filter, which will make the water treatment more efficient and trap unicellular algae from returning to the aquarium. In this case, the filter itself must be cleaned twice a week until the situation is completely normalized.
    • Use antibiotics, such as streptomycin or penicillin, to kill germs and purify the water. The drug must be crushed and dissolved in a volume of 3 milligrams in a liter of water, and then this solution must be introduced through a filter. This remedy is safe for the inhabitants of the aquarium and plants, but for the green euglena it is detrimental.
    • You can use coagulants used to filter drinking water, which help to effectively clean and aquarium. Suitable means “Hyacinth” or another with identical properties.

    Good to know: you can also use traditional methods, for example, boric acid. A 3% solution is added to the aquarium in a proportion of 1-2 milliliters per liter of water.

    What are the reasons the water in the aquarium turns green and what to do about it?

    Aquarium owners are well aware of how difficult it is to keep fish and maintain the conditions necessary for their existence. Why does the water in the aquarium turn green and how to deal with it? Find out the answers to these questions and get started.

    What to do if the water turns green quickly?

    If the water in the aquarium is blooming, then this problem should be resolved as soon as possible. Not everyone knows how this process affects fish, but it can lead to sad consequences.

    First, actively multiplying unicellular algae can enter the gills of aquarium inhabitants, clog them and disrupt respiration, provoking further death. Secondly, in troubled waters, fish feel extremely uncomfortable: they behave sluggishly, cannot reproduce and eat normally.

    Mechanical

    You can get rid of green water in an aquarium mechanically, which allows you to completely purify the water and remove blooming microorganisms from it.

    • Ultraviolet sterilizer. It neutralizes unicellular algae and inhibits their reproduction due to exposure to ultraviolet radiation.
    • Change the filter cartridges to others that have smaller holes and, accordingly, retain more impurities contained in the water.
    • In case of cloudiness and greening, an effective diatom filter can be used, which has a structure that allows you to trap even microscopic elements, including unicellular algae.

    Why does the water in the aquarium turn green??

    What makes the water green in the aquarium? One of the most common causes is euglena green, a type of unicellular algae that lives in many aquariums and is an integral part of the aquatic food chain.

    Normally, the number of such microorganisms should be maintained at a constant and moderate level, but under certain conditions, active reproduction begins, as a result of which the water acquires a greenish tint.

    Adverse factors provoking greening of water include:

    • excess organic matter in the water, for example, the remains of deceased inhabitants;
    • excessive lighting (direct sunlight or increased daylight hours up to 12-14 hours);
    • elevated water temperature (such a condition is considered favorable for the reproduction of unicellular algae);
    • insufficient filtration and contamination of water (algae and other impurities are not removed in time and accumulate);
    • insufficient aeration, that is, a decrease in the level of oxygen in the water due to breakdowns, failure or lack of a compressor;
    • excessive feeding of fish and other aquarium inhabitants (the remains of food settle to the bottom and rot, and because of this, the water becomes cloudy and green);
    • a large number of plants planted in the aquarium soil that violate the natural environment and the balance of organic matter.

    Preventive measures

    So that the water in the aquarium does not turn green, take several preventive measures:

    • Move the aquarium to a shaded area out of direct sunlight. But he shouldn’t be in a too dark place either.
    • If you use artificial lighting, then do not forget to turn it off at night and do not increase the length of daylight hours: it should be no more than 10-11 hours.
    • Monitor your aquarium at all times and carry out regular maintenance, which includes aeration and filtration of the water, as well as cleaning the walls and soil.
    • If necessary, periodically replace some of the water.
    • Control the amount of food given to the fish and do not increase it.
    • Take out dead aquatic creatures in time.

    Green water in an aquarium is a frustrating problem, but it can be solved if you act in a timely manner and use proven methods.

    Correct resettlement of underwater inhabitants from the aquarium

    In order to safely move the fish into another container, you must follow several important rules:

    • Monotonous water (in composition). It is necessary to make sure that the inhabitants of the aquarium do not experience discomfort when entering a completely new environment, therefore experts recommend diluting the new water with a small amount of the one in which the fish lived.
    • Temperature. Also, the absence of a difference in temperature is important, for this it is recommended to use a thermometer, since a difference of even 1 degree can play an important role.
    • “Independent decision”. It is advisable to make the fish swim from place to place by itself. To do this, it is necessary to catch it not with a net, but let it swim into a small container (for example, into a jar), then place this jar in its final destination and let the pet swim there on its own and explore the territory.

    Why does the aquarium turn green quickly

    Mechanical

    As auxiliary devices for water purification, you can use ultraviolet sterilizers, which are designed to fight various bacteria and protozoa, as well as ordinary ultraviolet lamps.

    Greenery on the walls and in the water of the aquarium: how it threatens

    Green water is a very unfavorable environment for fish. Algae, when breeding, can clog the gills of small aquarium dwellers. In addition, algae absorb oxygen, reducing its level to a critical level at night. As a result, the fish may suffocate.

    You need to know that you cannot put fish that have just been taken out of a clean aquarium or reservoir into green water.

    If you put them in a “blooming” tank, they can die. Filling the aquarium with “newbies” can only be done after cleaning.

    The water in the aquarium turns green: prevention

    Blooming water can be easily avoided by following some preventive tips:

    • do not put the aquarium near a window or other main light source;
    • feeding the fish should be controlled: you should remember the necessary portions and not exceed them;
    • it is necessary to monitor the cleanliness in the aquarium and remove rotten plants or other organic residues in time.

    So, coping with the appearance of a green tint in an aquarium is quite simple, moreover, this phenomenon can be prevented altogether. It is enough just to correctly arrange your living area, feed the fish in moderation, install all the necessary filters and be sure to regularly carry out preventive cleaning.

    Did you know? For a long time it was believed that fish do not make any sounds, but this is not the case. They communicate with each other using sounds in a wide range, which a person cannot hear.

    Aquarium care

    Daily maintenance of your aquarium includes:

    • checking the equipment for stability of work;
    • removing excess feed from the surface and bottom;
    • cleansing of algae if found.

    If the water is dirty, it is recommended to install a mechanical filter. It is not recommended to disturb the calmness of the fish unnecessarily.

    With a frequency of once a week, you need to change the water, and not completely, but only a third.

    If the water turns green or cloudy in the aquarium and an unpleasant odor appears, which, despite the efforts made, does not go away, you should clean the tank with a temporary eviction of the fish.

    The water in the aquarium turns green: what to do

    • Excessive flow of artificial and natural light into the aquarium. The fact is that small green algae, due to which the water in the aquarium turns green, is very fond of light. Therefore, in no case should the aquarium be placed closer than one and a half meters from the window and illuminate it for more than 10 hours a day with artificial lighting. It is because of the overabundance of light that green, small algae multiply, which spoil the water.
    • Excessive feeding of fish. The fact is that the fish eat exactly as much as they need. The rest of the feed settles to the bottom and begins to rot. It is because of this that the contents become cloudy, smell unpleasant, and the water in the aquarium turns green. Therefore, adjust the amount of food for your fish and do not overfeed them.
    • One of the reasons for the appearance of green water in the abode of fish is untimely, rare cleaning. Try to drain more water than during standard cleaning. If you want to stop the growth of green algae, you need to place the container with fish in complete darkness for 2-3 hours. Due to a lack of light, algae will stop multiplying for a while, their growth will stop. Accordingly, the contents of the fish house will turn green much slower.
    • Settle the inhabitants that eat green algae: daphnia, catfish.

    Green water in the aquarium

    • Be sure to place the aquarium more than one and a half meters away from sunlight. In summer, the lighting period should be 12 hours, and in winter 10.
    • Turn off the lights in the aquarium at night. This also inhibits the growth of algae.
    • Pour the soil into the aquarium on a slope, closer to the front wall. Under no circumstances should you take too much liquid from the aquarium when greening the water. By taking away water, you only activate the growth of green algae. Clean more often with filters and siphons.

    Anticoagulants for water are very helpful. over, this substance was originally developed not at all for fish lovers, but for people who monitor their health and improve water quality. The use of these funds has shown good results. All debris, green algae, nitrates and heavy metals are absorbed by the coagulant and settle to the bottom in a thick layer. The water in the container is clarified and becomes transparent. These additives are absolutely safe for the inhabitants of the aquarium.

    Maintaining an aquarium is not that difficult. You just need to clean it in time and adjust the lighting.

    • excessive water pollution due to untimely care;
    • improper lighting of the aquarium (excess sunlight);
    • excessive feeding of fish (excess food settles at the bottom, and then rots).

    To combat algae, you can use the tools at hand. For example, dilute 3 mg of streptomycin powder in 1 liter of water and introduce this mixture through a filter. This composition is safe for fish and plants, but at the same time detrimental to algae.

    Blooming water in an aquarium not only spoils its appearance, but also harms its inhabitants. In addition to reducing the concentration of oxygen in the water, plankton contamination causes clogging of the gills in fish. How to deal with this? First of all, you must adhere to a number of simple rules.

    • Protect the tank of the aquarium from strong exposure to light. It is necessary to adjust the brightness of the electric backlight and the lighting mode. The aquarium should be located at a distance of at least one and a half meters from direct sunlight. Winter lighting should last no more than 10, and in summer 12 hours a day.
    • Darken the aquarium for a while. For “blooming” water, which quickly turns green, a few “dark” hours are enough for excess microalgae to decay.
    • Populate the aquarium with organisms that eat harmful algae. These include snails, shrimps, catfish and daphnia. At the same time, daphnia are also food for aquarium fish at the same time. Therefore, in order for the water to be saturated with these living “filters”, it is necessary to launch daphnia into the aquarium, in a volume several times exceeding the norm of one feeding.
    • Change the water completely and check the aquarium equipment. Filters for water purification help maintain the necessary hygiene in the tank.
    • Regulate the amount of food consumed by the fish, as uneaten food settles into the ground and deteriorates, disrupting the biochemical environment in the aquarium.
    • Add special substances to the aquarium water that destroy the simplest algae. Among them, streptomycin powder is isolated, which is diluted in a small amount of boiled water and introduced into the aquarium through aeration.

    Caring for any pet involves carefully monitoring its health and maintaining cleanliness in its habitat. Fish, unlike cats or dogs, have to spend their entire existence in one container, so every detail of the ecosystem must work to maintain their health.

    • Improper lighting. Water bloom begins due to the fact that the roots and shoots of some aquarium plants begin to rot when there is a lack or excess of light.
    • Reproduction of euglena. This is the most common explanation for why the water in the aquarium turns green quickly if it has a small displacement. The small volume and abundance of plants create conditions for an accelerated increase in the number of euglena.
    • Rare cleaning of the aquarium. The film is removed from glass and decorative elements with a soft sponge and a safe cleaning agent at least once every 2-3 months, otherwise it “tightens” the water surface and filters.

    The solution to the problem in an aquarium that performs purely decorative functions seems to be simpler than if fish live in it. Those of them that appeared in it before the flowering of water may refuse to eat and suffer from lesions of the scales due to turbidity. Fish transferred to it from a clean container often die in the first 2-3 days due to a sharp change in microflora.

    • Poor quality feed. Cheap live food from bloodworms or daphnia can be rancid, and dry flakes often contain second-rate wheat as a base. Food pollutes the water and creates all the conditions for the multiplication of pathogenic bacteria.
    • Organic waste. Uneaten food settles to the bottom of the aquarium, as do processed food particles. The answer to the question of why the water turns green lies in the recommendations for the timely cleaning of this waste.

    Since plants are considered one of the main causes of water bloom, many inexperienced aquarium owners are stunned by the appearance of duckweed on the surface of an aquarium in which hydrophytes do not live. Green water in an aquarium without plants is a signal, if not for cleaning the fish, then definitely for replacing the filter or its parts. Microorganisms settle in the tube and on underwater mountings, creating rotting and fetid odor of water.

    Changing the shade of the water in the tank that the turtle lives in sometimes has nothing to do with its diet and lighting settings. Cloudy green water in an aquarium can be the result of one of two conditions:

    • Insufficient fluid level in the turtle. Algae with strong growth cannot live above the water surface: they fall off and die off, and their decay products create a thin film.
    • Features of the body of a turtle. Red-eared turtles quickly process food and defecate more often than other species. Experienced turtle breeders, therefore, advise to transfer them during feeding from the aquarium to a small basin.

    When a film and duckweed appear, the underwater world should be protected from a potential focus of infection. Experts advise to carry out preventive examination for flowering 2-3 times a week. If green water does appear in the aquarium, you need to decide how to deal with it. Before making this decision, it is necessary to stop the spread of the slimy film:

    • Fish and plants are transferred to two different containers with clean water.
    • Rocks and other parts of the aquarium are washed with a brush or hard sponge.
    • The walls of the aquarium are scrubbed with a magnetic scraper or a disused credit card.

    The water in the aquarium turns green: what to do

    Natural cleansing means eradicating the cause of the multiplication of green microalgae:

    • Protecting the aquarium from light. Green algae cannot continue their vital activity in the dark, you need to completely turn off all lighting, and if necessary, even glue the walls of the aquarium with light-transmitting film or paper. Pisces may well live without light for some time, so you should not worry about your favorites. Light “quarantine” should last at least a week.
    • Cleaning from organic residues. For such purification, it is necessary to filter the soil, remove all dead plants, and also install more powerful aquarium filters. Also, feeding the fish must be minimized (feed, if necessary, with a small amount of food and watch out for its instant eating).

    Important! During the period of light deprivation, oxygen must be supplied at maximum, since the absence of light must be compensated for by a large amount of air.

    Natural cleansing

    Plaque formed on the walls of the aquarium can be destroyed by live “orderlies”, for example, catfish. Snails, platies, mollnesia can take part in cleansing. Planktonic crustaceans become frequent inhabitants of aquariums, which also cleanse the reservoir of microorganisms by passing and filtering water through themselves. If the choice of the aquarist fell on crustaceans, then populate them in large numbers, since these creatures always become a delicacy for predatory fish.

    Living “filters” are able to remove greenery from decorations, walls of the aquarium, soil. This method will become even more effective if for the period of cleansing you reduce the portion of food for the fish, reduce the length of daylight hours and turn on the aeration systems at high power.

    How to deal with it?

    When the bloom of aquarium water has become serious, it is required to relocate all residents. The fish can be temporarily placed in another tank with the same water parameters. For plants, a container is enough, where methylene blue is added. If the water is just beginning to turn green, then it is possible not to expose the aquarium inhabitants. Fighting green algae can take time. This can be done in different ways.

    Traditional methods

    Some aquarists turn to folk recipes for help. For example, a 3% solution of boric acid can overcome greens. The drug is added to the aquarium in a proportion of 1-2 ml per 1 liter of water.

    Chemicals

    Experienced fish lovers prefer to combine the mechanical method and the use of chemicals. The introduction of chemistry helps to suppress the development of phytoplankton. The most popular remedies are as follows.

    • Hyacinth. According to the instructions, the drug is added to water in a ratio of 1 ml to 10 liters of water. As soon as microorganisms die under the influence of the agent, they are eliminated by the filtration system.
    • Streptomycin. It is an antibiotic. Eliminates any type of unicellular algae. Diluted at 3 mg per liter of water.
    • Erythromycin. Also belongs to the class of antibiotics. To combat phytoplankton, you need to add 250 mg of the drug per 100 liters of water.

    Why green water is dangerous?

    Every aquarist is probably familiar with greening water. The phenomenon is the uncontrolled development of phytoplankton. The artificial reservoir acquires green color under the influence of the abundance of pigmented cells. Sometimes the color of the water can turn yellow-brown or reddish. Phytoplankton can be compared to ordinary algae, which, unlike known plants, does not grow on the walls of the aquarium, but multiplies in the water column.

    You should not be very afraid of him. Small amounts of these microscopic organisms will not harm aquarium inhabitants, but they can disrupt the biobalance by taking useful elements from aquarium plants. In the process of proliferation, phytoplankton changes water parameters and worsens the development of green spaces, as a result, this process leads to a significant reduction in oxygen in the water, and this can already negatively affect the state of animals and fish.

    The danger of green water lies in the fact that as phytoplankton multiply, the reservoir becomes more and more turbid, and soon it becomes impossible to see the aquarium world through the green haze. The owner may not notice the poor condition of the fish in time and miss their illness.

    Finally, greening in the aquarium significantly spoils the appearance of an artificial reservoir, makes it unkempt, abandoned.

    Mechanical method

    To get rid of greenery mechanically, heed the recommendations of experienced aquarists.

    • Put a high-quality filter in the tank, the power of which corresponds to the volume of the tank. Clean all hoses, tubes and sponges that make up the device regularly. If it is an outdoor unit, it may need to be cleaned less frequently. Internal filter needs cleaning weekly.
    • To reduce the spread of unicellular algae, install a special ultraviolet sterilizer, also equip the aquarium with a diatom filter, which will more effectively clean the artificial reservoir of harmful microorganisms.

    Remember to periodically scrape off green plaque from surfaces.

    Main reasons

    There are several reasons for this problem. Most often, the following factors lead to greening.

    • Excess organic components. During decay, the waste products of aquarium inhabitants, dead leaves and parts of exfoliated shells release nitrogen compounds into the water, which phytoplankton feed on. The more decaying fragments, the faster the unicellular algae spreads, and the faster the water turns green. You can find out what the abundance of organic matter led to the negative process by a large amount of fish excrement and the remains of molting of armored animals. By the way, this process not only provokes the development of microorganisms, but also becomes source of poisoning in the reservoir, which reduces the quality of water.
    • Excess light. One of the most common reasons. Usually, the water turns green in the aquarium, which is located under ultraviolet rays. That is why aquarists forbid placing the container on the south or southeast window. Powerful lighting equipment that works longer than 12 hours a day also leads to the development of microalgae.
    • Defective filter. Weak filtration systems can also cause the water to turn green. A poorly working filter, designed for a smaller volume than is actually used, is unable to fully eliminate contamination. Uncleaned debris becomes a tasty food for unicellular algae. A filter that is rarely cleaned leads to the same process.
    • Abundance of vegetation. Until the lighting is turned on, plants are engaged in the production of carbon dioxide in the dark. This element is extremely important for the development of phytoplankton. In this regard, a large number of green spaces leads to the multiplication of microorganisms.
    • Elevated temperature. The optimum temperature range for aquarium animals and plants is 22-26 degrees. With an increase in performance, unicellular algae spread very quickly throughout the entire water column. The cause can be identified by looking at the aquarium thermometer.
    • Bad cleaning. This causes not only the reproduction of algae, but also fish diseases. Cleaning should be of high quality and regular. The smaller the tank capacity, the more frequent cleaning it needs. So, a 15-liter aquarium needs to be cleaned weekly, and a 100-liter artificial reservoir requires cleaning once a month. The process consists in cleaning the walls from green plaque, thinning and pruning overgrown plants, cleaning the soil siphons, cleaning the filter.
    • Incorrect replacement. The novice aquarist is not immediately involved in the process of caring for the aquarium and at first may change part of the water too rarely or often. And in fact, and in another case, the reproduction of unicellular algae is possible. It is important to take water changes responsibly.
    • Poor fish feed. Poor food powder, half-eaten by fish, settles to the bottom, where it begins to decompose. This process becomes a factor in the spread of a colony of microscopic algae.

    Why does the water in an aquarium turn green and how to deal with it?

    A responsible aquarist, noticing a slight greening of the water, will not wait for the greenery to cover the entire space of the tank, but will try to solve the problem as soon as possible. But first, it is important to find out what caused this phenomenon and eliminate the root of the problem, and then regularly take preventive measures.

    An overabundance of organic matter

    Organic matter includes fish residues, dead particles of aquatic plants, tiny pieces of shrimp and snail shells. All these components quickly decompose and actively release nitrogenous compounds, which, in turn, become food for algae.

    The more organic matter is in the tank, the more rapidly algae grow and multiply, coloring the water in a green tint.

    It is possible to understand that the reason for the excess of organic matter is the presence of a significant amount of residues of the “molting” of aquatic inhabitants and excrement. Filling the aquarium with waste not only leads to the rapid growth of algae, but also poisons the aquatic environment, reducing the quality of life of the fish.

    • To thin out the dense population. Transplant some of the animals to other banks.
    • Adjust the feeding and do not forget to immediately remove the remnants of not eaten food.
    • Siphon the bottom of the aquarium.

    Mechanical cleaning

    To do this, the aquarist should get a powerful filter, but in accordance with the volume of the aqua and do not forget to regularly clean the filter sponges.

    You will also need other equipment:

    Providing a better, more complete purification and disinfection of water.

    Capable of regulating the number of microscopic organisms.

    The main reasons for green blooming

    Green water is evidence of rapid reproduction of unicellular algae in the domestic aqua system. Euglena is growing especially actively. the simplest microorganism, characterized by the ability to survive in almost any conditions. over, Euglena green can grow both under light (with the presence of photosynthesis), and in the dark, feeding on bacteria. Coping with the parasite is difficult, but doable.

    There are several catalysts for this phenomenon. To successfully deal with herbs, you need to find out its source and remove the culprit. Let’s take a look at the main reasons why the water in an aquarium turns green.

    Effective ways to combat green water

    But what to do if the reasons why the water in the aquarium turns green seems to have been established and destroyed, but the flowering processes are still observed?

    If greening has grown into a global phenomenon, then you will have to do the following:

    • Temporarily transplant aquatic inhabitants into another container (make sure that the characteristics and parameters of the water are similar).
    • Place aquatic plants in a container filled with water with the addition of methylene blue.
    • Remove all decor from the aqua and rinse thoroughly. Do the same with the equipment.
    • Rinse the tank completely. Pour the previously settled water into the aquarium and return the plants and animals to their place.

    You can use other methods as well.

    Chemical cleansing

    In extreme cases, you can resort to specialized drugs that will quickly help resolve the issue of why the water in the aquarium turns green.

    The best remedies for experienced aquarists include:

    It is introduced at the rate of 1 ml of coagulant per 10 liters of water (when using hyacinth, microorganisms die within a day, their residues are removed through filtration systems).

    The antibiotic is added to the container in a volume of 250 mg per 100 liters of water.

    The antibiotic is added in the amount of 3 mg of the product for each liter of water.

    Tetra AlgoStop-depot tablets

    Slow-dissolving tablets, they dissolve in water within a month, gradually clearing the entire container.

    Tetra AlguMin-Plus special solution

    All of these drugs are harmless to aquarium inhabitants, they can be used once.

    Natural cleansing

    To achieve good results and to get rid of active algae naturally, the aquarium needs orderlies:

    • catfish that actively eat plaque on the walls of the container and decorations;
    • snails and fish of the breed of pecilia and mollies, which also willingly feast on microscopic algae;
    • planktonic crustaceans, they let water through themselves and naturally purify it.

    To stimulate natural orderlies to be more active, temporarily reduce the diet, shorten the duration of lighting and increase aeration.

    What is the danger of flowering

    A small bloom does not bear some kind of global catastrophe for underwater inhabitants.

    If the problem is not resolved in time, the flowering will acquire large-scale dimensions, the consequences will be as follows:

    • The amount of nutrients in the water area will decrease.
    • Decreased oxygen levels.
    • An imbalance in the aquatic ecosystem will appear.
    • Some fish may die, others, more persistent will begin to get sick and wither.

    The presence of green water is a clear indication of an imbalance in the aquatic environment, such a violation will not disappear by itself, the problem of why the water in the aquarium turns green should be addressed immediately.
