How much water should be infused for the aquarium

When the procedure is not needed?

The water does not need to be defended when a reverse osmosis filter is used. This is not only protection against chlorine compounds, but also guaranteed absence of heavy metals in water.

There are also emergency situations when water needs to be used directly from the tap:

  • much, water, infused, aquarium

    Choking fish. Lovers of aquarium plants know the consequences of an incorrectly configured carbon dioxide supply system. Too low a pH and a lack of oxygen can kill fish in a matter of hours. In this case, an emergency change of cold tap water can save the situation.

  • Overheat. In the summer, many aquarists are faced with an uncontrolled rise in the temperature of the aquarium water. The warmer the water, the worse the gases dissolve in it, and the oxygen necessary for the inhabitants of the aquarium is no exception. Therefore, sometimes replacing cold water from the tap (and in it a high level of oxygen) saves the life of the fish.
  • Infections. Fish also tend to get sick. In addition to medication, a small tap water change will help them cope with infection.

Volume and frequency of substitutions

Most aquarists adhere to the classic scheme of changes in aquariums. once a week at 30%.

But it should be borne in mind that this is a generalized rule, and each tank has its own nuances:

  • For a dispersed herbalist, 30% is not enough. Fans of underwater plants are forced to change up to 50% weekly, this will wash out excess nutrients and prevent algae outbreaks.
  • An aquarium with large fish also needs more massive changes, but since the fish can experience stress from fresh water, it is better to do two changes per week, 25-30% each, this will reduce the load on the biological system.
  • Shrimp. aquariums that require maximum stability of water parameters and sustainable biological balance, so a weekly change of 10% of the volume will be sufficient.

We prepare water for fish. how much and how to insist before pouring

Many aquarists prefer to let it brew before pouring water into the aquarium.

In most regions, tap water is not of the best quality, so in some cases this is really justified. This procedure helps protect the inhabitants of the home reservoir from poisoning with poisonous chlorine.

How much should be infused?

Chloramine disappears after a few hours, chlorine. about three days. Despite the fact that chlorine is rarely used, as a rule, in cases when an outbreak of any infectious or viral diseases is noticed in the region, filter stations rarely inform people about the decision to use chlorine.

Therefore, to be sure, it is better to leave the water for three days, or even better, arrange an air purge using an aquarium compressor. Then it will be usable the very next day.

It is almost impossible to determine the readiness of the water without using a special aquarium test, because if chlorine has the usual whiteness smell, then chloramine does not smell. But it is not necessary to do tests if the water has stood for 2-3 days, since all harmful gases have already evaporated.

Alternative methods

For those who do not have time for such manipulations with buckets, there are several alternative methods of water treatment:

  • Boiling. During boiling, water reaches the maximum level of gas exchange, and chlorine-containing gases evaporate instantly.
  • Special conditioners. Tetra AquaSafe, Aquayer Antichlor, Mosura Shizem, etc.
  • Using osmotic or distilled water.

Harvesting tap H2O

There is a main rule of settling water. the larger the surface in contact with air, the better.

Therefore, plastic bottles with a narrow neck should be discarded. The best option would be buckets, pots and basins.

The fact is that chlorine is a gas, and the larger the surface area of ​​the water, the faster this gas will come out.

Do I need to do this?

The water should be infused for several purposes:

  • Equalization of temperatures. When the water settles, it cools or heats up to room temperature, and if it is poured into the aquarium, then in most cases, the fish does not experience the shock of a sharp jump in temperature.
  • Chlorine weathering. Tap water is disinfected: either chlorine or chloramine is added to it at filter stations.

Both of these substances are very dangerous, chlorine. kills the bacterial environment of the aquarium, can cause poisoning of fish and is detrimental to ornamental shrimp, it takes a long time to erode.

Chloramine is a compound of chlorine and ammonia. Water disinfected with chloramine, once in the aquarium, breaks down into chlorine and ammonia or ammonium (depending on the pH level in the aquarium), that is, in addition to dangerous chlorine, the fish also runs the risk of poisoning with a sharp jump in nitrogenous compounds.

At low concentrations, chloramine is not as harmful as chlorine, but it actively provokes the growth of unwanted algae.

  • PH equalization. When water is collected in a container, gases actively dissolve in it: oxygen, carbon dioxide, they affect the pH, therefore it is better to allow these gases to disappear, and then the acidity will stabilize. This will protect the fish from fluctuations in pH, since many aquatic organisms react very painfully to a sharp change in this parameter.
  • Instructions

    It is worth preparing for substitutions in advance. To properly prepare water, you should pay special attention to this issue.

    How and how much water should be defended for an aquarium?

    For most modern people, the main source of water for any need is running water. Any adult has heard that the liquid from there, to put it mildly, does not correspond to the best ideas about its quality. chlorination, which is the main method of cleaning, adds far from the most useful chlorine, the quality of cleaning often leaves much to be desired, and when passing through rusty communications, water re-clogged with all sorts of unpleasant things.

    Even a large and strong person who simply occasionally drinks such water puts his health in danger.

    One can only imagine how destructive the constant stay of fish in such an environment is. For this reason, it is imperative that many aquarists defend the water before it enters the aquarium.

    Required water parameters

    As for humans, polluted air is unpleasant, so fish cannot live in polluted water. Therefore, the latter must meet certain requirements if you value the life of your pets.

    In fairness, it should be said that different biological species can put forward different requirements, so the generalizations below are comfortable for most species, but not for all. We specifically focus on those species of fish that beginners usually start with, while they do not really understand how to properly take care of whimsical species.

    One of the most important criteria is the acidity of the liquid. Both acidic and alkaline ions are present in water, and if they are equally divided, the environment is considered normal, that is, neutral. This is what is considered ideal for the normal functioning of most aquarium animals and plants.

    The acidity level is indicated by the letters pH and a number, if we are talking about a neutral medium, it will be described as pH 7.

    Deviations to either side are undesirable for an average fish, and the more significant they are, the worse.

    It is not in vain that this criterion comes first. settling does not affect it in any way, which means that moisture must be initially chosen correctly.

    Another important criterion is rigidity. It directly depends on how many “foreign” substances the water was able to dissolve in itself before it got into your sump. Most often, an increase in the level of hardness ensures the presence of dissolved calcium in the moisture.

    Unlike many other substances dissolved in a liquid, calcium (in a normal dosage) is even useful for fish, since they form “details” of their body from it. Each species requires a certain level of hardness, which it is desirable to observe, while the fish and plants gradually extract calcium from the moisture, making the latter softer.

    So that the water does not lose the required characteristics, chalk, limestone or shells, as well as magnesium chloride or soda, must be added to it. In this regard, overly avid upholding can even harm.

    Another impurity that stays in a liquid in a dissolved form is salt of various origins.

    The inhabitants of the aquarium can extract minerals dissolved in salt water for their needs, therefore the aquarist must ensure that the salinity inside the artificial reservoir is always maintained at the same level.

    How long will it take?

    On the Internet, you can find a variety of tips on how long it takes to defend tap water from the tap. there are even absolutely fantastic values ​​indicating that the exposure should be up to ten days.

    If you doubt the adequacy of such recommendations, you are right. the result appears much faster, and the further procedure does not bring any visible benefit.

    As mentioned above, liquid impurities or additives that are dissolved in water will not be removed by any sedimentation. here you can not even hope.

    Gaseous impurities in their bulk are removed from the water almost instantly at the time of recruitment, and this happens especially quickly if moisture is collected correctly. we will talk about this in more detail in the next section.

    The situation with solid impurities is somewhat more complicated. First of all, according to current regulations, they should not be in tap water at all, but this, of course, is an unattainable ideal. rusty metal pipes, gradually decaying, emit the smallest crumbs of rust, which, together with moisture, enters the aquarium. If you are sure that your water supply system consists entirely of modern plastic pipes, then there really should not be any impurities, but at least for the first time, you need to check the liquid for sure.

    It is enough to leave the water for just an hour and see if there are foreign impurities in it or not. the minimum sediment, if it is expected at all, will already appear by this time.

    At the same time, the appearance of some sediment does not yet mean that the moisture has cleared. it is believed that it needs to settle for 12-24 hours so that the predominant part of the harmful components goes to the bottom.

    In some cases, when the liquid is particularly turbid and dirty, it can be allowed to stand for 2 days, but it would be better to find another source. It is generally accepted that a proven source, from which you have repeatedly taken water for an aquarium, can not be checked strenuously. figuratively speaking, the same 12 hours should be enough.

    Please note: even if you did not notice the problems, standing still will not hurt, just its duration can be shortened.

    However, even in such a situation, experienced experts advise periodically rechecking the moisture. in nature there are no constant values ​​of purity, which means that foreign impurities could get into your water supply system or well.

    Fish Tank Water Changes 101: How Much Water Should You Change in Your Aquarium?

    When collecting water from a specific source for the first time, it is necessary not only to extend the settling period, but also to closely monitor the precipitation in order to learn more about the properties of moisture.

    When taken from natural reservoirs or wells, the liquid often turns out to be cloudy due to the suspension of silt and sand, which is inevitably present in it.

    If there is confidence that it is silt and sand, then there is no special need for their removal and settling, since they do not harm the fish, because it is the norm for it to live in such conditions.

    The only reason why this can interfere is the inability to admire pets due to constant turbidity.

    Sand, as a rule, settles itself rather quickly, but in order to “calm down” the clay, you need to plant plants with a branched root system in the aquarium, which perfectly retains this substance.

    What is it for?

    Even if your source of moisture isn’t from the plumbing, that doesn’t mean it’s good for the aquarium. Harmful impurities can be present even in the reservoir, which has not been affected by anthropogenic impact. After all, not all bodies of water are suitable for living creatures and not every species of fish can be sensitive to some kind of irritant that is not critical for other species.

    Trying to settle the liquid from a familiar source, you can observe various interesting phenomena when it becomes cloudy or a precipitate falls out in it, which has not been observed before.

    The main goal of aquarists is to remove foreign substances that will definitely not benefit scaly pets.

    Funnily enough, a significant percentage of fish breeders regularly perform this ritual, but no one really knows exactly how much water needs to be defended. Plus, you don’t need to be a genius to understand the obvious. advocating doesn’t solve all problems. Often, even after it, the liquid may still remain unsuitable for normal fish activity.

    Having sifted out myths and idle fictions, we come to the conclusion that there are three types of pollutants in water, and representatives of each type can react to sedimentation in different ways:

    • solid impurities precipitate and remain at the bottom, while the cleaned top layer of water can be carefully drained;
    • gaseous impurities are light, therefore, in an open vessel, they can escape into the atmosphere;
    • liquid components, unfortunately, are not removed from the water by settling.

    Correct settling

    Only at first glance, a person does not actually take part in defending.

    In fact, you can get almost perfect water at home, or you can defend the liquid so incorrectly that no long periods of time will give the desired effect.

    Using a simple example, you can see possible errors by considering how to properly remove chlorine gas from tap water.

    • The gas particles are scattered throughout the volume of the water, and your task is to bring them in direct contact with the air to ensure complete gas evacuation. You can help this process already at the stage of pouring water. for this it is advisable to collect it in a container for settling with a powerful jet, since at the moment of impact, moisture will push out gas bubbles from its bowels.
    • The larger the area of ​​contact of the water surface with the atmosphere, the faster and more efficiently the release of any gaseous pollutants, including chlorine, will occur. In a bottle with a narrow neck, only a small percentage of water will come into direct contact with air, which means that a lot of bubbles can remain somewhere in the thickness of the bubbles. It is most reasonable to settle the liquid in a wide vessel.
    • Covering the container for settling with a lid, you impede normal gas exchange, so chlorine, even when released from the water, simply has no way out to leave the container. Diffusion has not been canceled, chlorine in a closed space can again penetrate into moisture.

    Ordinary settling does not give the slightest effect when removing liquid impurities, but the modern chemical industry is able to solve other problems.

    There are special conditioners that bind molecules of such harmful compounds as ammonia, nitrites, chloramine or hydrogen sulfide. in this form they will be separated from water and still precipitate.

    A slight difficulty lies in the fact that in order to choose the right conditioner, you must know what substances can be dissolved in moisture, so as not to add extra “chemistry” where there is already an excess of it.

    To clarify what threats are typical for water bodies in your region, you can in the sanitary and epidemiological station, they will also tell you what exactly should be used to purify the water.

    The settling time depends on the selected air conditioner and the degree of pollution, but one day should also be enough.

    • Do not get carried away with frequent water changes. by putting sedimentation on the conveyor, you will be constantly in a hurry, so sooner or later show an unforgivable disregard for this procedure than harm your pets. If you have not overcrowded your own aquarium, then the big problem is that there is no flow inside and there is no constant renewal of fluid, it will not happen, but various beneficial microorganisms that break down nitrates and nitrites will be able to multiply.
    • If the water in the aquarium becomes cloudy after a few days after replacement, this is normal, but it indicates that the moment of the next exchange has nevertheless come. The fact is that the waste products of living organisms get into the water, which is the reason for this phenomenon.
    • Even if you constantly use water from the same source, in modern conditions you cannot be sure that it will be the same day after day. You may not notice the difference, and new impurities (or the absence of old ones) by themselves might not be a problem for the fish, if not for one “but”: they may not like the abrupt change in living conditions. For this reason, experienced aquarists try not to change all the water at once, leaving about 2/3 of the old liquid. This approach allows you not to disturb the biological balance, because otherwise the population of bacteria that break down the waste of the inhabitants of the aquarium may die.
    • Almost the only situation in which it is possible and necessary to fill in completely new water is a complete cleaning of the aquarium from contamination. Of course, the aforementioned colonies of microorganisms will die, but theoretically they should have disappeared anyway during the cleaning process, so there is no point in taking risks and leaving the old dirt.
    • In some situations, there is no way to wait for the water to settle and the aquarist has to fill in the unsettled liquid. This is better than giving up the moisture cycle altogether. But such a move is allowed only in extreme cases, and in volumes not exceeding 1/5 of the aquarium.

    You can learn how to change the water in the aquarium from the video.


    Not all people understand why it is necessary to defend water at all. In fact, this is an incredibly important procedure during which many processes take place. The fact is that any tap water has an extremely rich composition, and often it contains many hazardous substances and impurities that can harm both humans and underwater animals.

    Chlorine is the first to escape. This happens in a few hours, but if you wait longer, you will see sediment in the container, namely, particles of solid metals that have settled on the bottom. That is, sedimentation has one single purpose. to make tap water safer and more suitable for fish.

    In general, three types of impurities and substances accumulate in water:

    • Solid. Fall out in a few days in the sediment;
    • Gaseous. Escaping into the air;
    • Liquid. They are initially already dissolved, and therefore it will not be possible to get rid of them.

    That is, settling helps to get rid of the first two components, but does not affect the latter in water at all. But, nevertheless, it is still necessary to defend it.

    Not all beginner lovers of underwater flora and fauna know how long it takes to defend the water. Completely harmful substances are released in 1-2 weeks (the duration is influenced by the characteristics of the region and the quality of the water itself).

    The best container is a basin or bucket. That is, the surface area is important, not the volume. If there is no such amount of time, then you need to withstand the liquid for at least a couple of days. But in this case, it is advisable to use special drugs that neutralize harmful compounds.

    How to defend water?

    There is nothing complicated in this procedure. It is enough to prepare the required number of containers. The best option is basins, buckets, etc. The most unsuitable are bottles, eggplants and other similar containers with a narrow neck. The area is critical. The larger it is, the better the gas exchange will be, and, accordingly, the faster the substances will leave the water. The whole process looks like this:

    • We collect water from the tap into the prepared containers;
    • We cover them with gauze (in no case with a lid);
    • We leave containers for a period from several days to a couple of weeks. This depends on the region where the aquarist lives and the quality of the tap water;
    • We remove the gauze, pour the contents into the aquarium, but not completely, since there will be a sediment of heavy metals at the bottom.

    If we are talking about starting an aquarium, then you can simply fill it like this, and when the water is ready, add unpretentious plants like hornwort there.

    Water parameters

    An aquarium is a real ecosystem. The water that was poured into it contains many different compounds, bacteria, etc. Even the collected water is not exclusively H₂O. It has its own characteristics. So that fish and other pets do not get sick, they are comfortable, the aquarist needs to create optimal water parameters.

    In general, a lover of underwater flora and fauna is faced with different characteristics when working in an aquarium. For example, this is acidity (pH). This is the pH value of an acidic environment. The neutral value is 7 pH. It is the most versatile and suitable for most plants and animals. If the acidity is less, then this indicates a high alkalinity of water, if more, then, accordingly, it is considered acidic due to the high concentration of dissolved minerals.

    It should be noted right away that pH is a very flexible parameter, since it can change and, in general, it is influenced by a lot of factors. This is aeration, temperature, the presence of decor, soil, plants, the level of nitrates, hardness. This indicator affects exclusively the well-being of the fish, since each species has its own preferences.

    The second most important parameter is hardness (dH). It depends on whether the aquarist can get certain plants or fish. Hardness is a collection of a number of compounds in water such as calcium, magnesium, carbonates, biocarbonates. It has a huge impact on the aquarium:

    • Calcium and magnesium contained in water are necessary for the formation of the skeleton in fish;
    • These same substances make the shells of snails, shrimps and crabs harder, which is vital for these animals;
    • Well, and of course, this indicator determines how quickly certain plants will grow.

    The normal dH reading is 5-25 degrees. The hardness is measured using standard tests or laundry soap.

    It is also possible to change dH if desired. If it needs to be raised, then shells of crustaceans or molluscs, as well as chalk, coral chips or limestone, are thrown into the aquarium. To reduce it, you can add a distiller or use melt water when changing. Plants such as elodea or hornwort can also be thrown into the aquarium.

    Rapid settling of water

    The easiest and most effective way to prepare your water is to use an aquarium conditioner. Today there are many different dry cleaning products. Their principle of operation is that they react to harmful substances and neutralize them. The most popular are Tetra AquaSave, Aquier AntiToksin Vita and Sera Aquatan.

    Tetra Aqua Safe Water Conditioner

    In fact, these three drugs are analogs and equally affect the composition of water. Their advantages lie in the fact that with them you do not need to defend water for days and weeks. In addition, they effectively remove all aggressive substances and, just as important, additionally protect the mucous membrane of fish, thereby reducing the level of stress in animals.

    Can I use bottled water?

    This is theoretically possible. The main advantage of this option is the stability of the mineral composition of this product. However, in order to pour purchased water into the aquarium, you must be sure that it has the correct composition.

    The fact is that humans and underwater animals have completely different needs for water. Plus, we have a more flexible immune system than fish. Therefore, the decision is entirely up to the aquarist. If he is confident in the purchased product and conducted tests (the declared parameters on the label often do not correspond to reality), then such water can be poured into the aquarium. But if there are doubts and there is no desire to take risks, then it is best to just defend the tap water. Although it has worse properties, the fish adapt to such parameters and, ultimately, this will not affect their health. Here, as they say, the best is the enemy of the good. Trying to improve the living conditions of your underwater pets, you can, on the contrary, harm them with such changes.

    How to properly defend water for an aquarium

    When launching an aquarium, we take into account a lot of different nuances, so that as a result, a full-fledged underwater living corner appears at home. In this process, you need to perform a lot of different operations, but the most basic and obligatory is the settling of water. It would seem, what can be difficult here? I made supplies in eggplants, buckets, a tank or a saucepan, waited, and poured everything into the aquarium. But here, too, there are subtleties with which even experienced aquarists are sometimes unfamiliar.

    Water change

    A weekly water change is a process that every aquarist has to deal with. This is an extremely necessary procedure, as it allows you to keep the aquarium clean and at the same time protect the animals from harmful substances.

    In every home underwater world, different processes take place. Fish leave behind waste products, plant leaves rot, and sometimes there are food residues. As a result, nitrates and phosphates remain in the water. Of course, they are assimilated by living plants, but the flora does not always have time to absorb all the dangerous compounds.

    If the aquarium was launched recently, then beneficial bacterial colonies might not have formed in it yet, and in this case, ammonia is formed in the water, which can kill all living things in the “jar” in a short time.

    In all such cases, one of the simplest and most effective ways to combat is substitution. It is desirable to conduct them every week, about 25-30% of the total. We collect water using any of the above methods.

    It is also worth mentioning the water changes in the new aquarium. This must be done, but carefully. It is better to look in advance for information on how to properly launch the “can”, when and how much water needs to be added. This is mainly necessary to reduce the concentration of ammonia, nitrites and nitrates, since there are no bacterial colonies in the new aquarium yet, the plants have not yet adapted and do not fully perform their useful functions. Therefore, the aquarist can only prevent unwanted consequences by gradually adding fresh water without hazardous compounds.

    A common cause of cloudy water in an aquarium is a bacterial outbreak.

    Sometimes it happens that the water becomes cloudy after a change. Often this process only means a bacterial outbreak. In the aquarium, organics appeared earlier, provoking the reproduction of ciliates. With such an excess of food, it actively reproduces, and this is manifested by the fact that the water becomes cloudy. For novice aquarists, there is only one reaction to this. a quick substitution. However, this is the wrong move. The fact is that there will also be nutrients in the new water, and, accordingly, this will provoke even greater reproduction of the ciliates.

    Better, on the contrary, not to do this. If the substitution was nevertheless carried out, then you need to be patient when the food in the aquarium runs out and the bacteria begin to die. As a result, the water will be cleaned by itself, without outside interference. This process usually takes a day or two (depending on the degree of turbidity).

    Reservoir with settled rainwater

    Rainwater is also used in a fish tank. Previously, such water was used for food, but nowadays it is not particularly useful (except for the one that falls in ecologically clean regions). It contains impurities of toxic substances and parasites, so sedimentation and powerful filtration are necessary. Rainwater can contain substances that are not washed out of the air. It receives contamination from pipes, gutters, pipelines, roofs and other surfaces from which it flowed out.

    For aquarium needs, rainwater is not always suitable. improper treatment of the liquid harms the fish. How long does it take for the rain to settle? After filling water in a clean glass container, install a powerful filter in it, treating the liquid for several hours. After cleaning, leave the water in a cool place for a few days. However, the risk from such water is great. its use is possible only after laboratory tests.

    How to prepare an aquarium with tap water

    The easiest and cheapest way to stock up on water is to draw tap water into a tank. It is available to almost everyone, suitable for any freshwater aquarium. It is not harmful to fish if properly defended. If a high-quality tap water purifier is not installed in your home, the collected liquid cannot be immediately poured into the tank. Chlorine compounds found in water must be vented within a few days. Why do this? To protect fish and plants from poisoning and premature death.

    You can take water directly from the tap into glass jars, and leave it for 3-4 days, covered with gauze. All volatile compounds will evaporate and the liquid will become colorless and free of chemical compounds. It is necessary to check the collected water for smell and color. Chlorinated water smells harsh and has a milky white color.

    See how to gently pour the settled water into the aquarium.

    About water preparation

    Novice aquarists are interested in how to prepare water for an aquarium. It will be necessary to purify the water by settling at least from solid impurities, but before using it, you will still need to add special cleaning agents. It is also necessary to measure the pH and temperature. To measure the pH level, stock up on paper indicators. Regular baking soda can help raise the pH, peat can lower the pH.

    In order not to waste time on settling and measuring the acid-base balance, you can take distilled water for the aquarium, but this is recommended only as a last resort and with a small aquarium volume. Do not abuse distilled water: it does not contain not only harmful, but also useful impurities for the inhabitants of the aquarium.

    How much water should settle to start the fish? aquarium from scratch

    About 10 days. It’s not about water, it can be removed from chlorine and other impurities with an air conditioner, but the biobalance.
    “The first day.
    1. Place the aquarium on the stand, replace the lid and turn on the aquarium lamps to make sure they are working. You will need lighting only after a week, but you need to make sure in the operation of electrical equipment in advance. In addition, you will need light to lay the ground and shape the design of the aquarium.
    2. Clean the aquarium with baking soda or other non-toxic detergent. Never use household chemicals for flushing. If the aquarium is small, you can fill it, rinse it without chemicals and drain the water.
    3. Install the equipment (usually a filter, compressor, heater) and check its operation.
    4. Fill with soil. If an uneven bookmark is required. do this on an empty aquarium. then it will be more difficult. If heavy decor with sharp edges is intended. it is advisable to put plexiglass or foam on the bottom before filling the soil.
    5. Install stones and driftwood.
    6. Install and decorate air compressor filters and tubes.
    7. Install the thermometer.
    8. Fill the aquarium with cold water. To prevent soil erosion, place a saucer on the bottom of the aquarium and pour water over it in a moderate stream. If you are using a water inlet hose, then a shower head will not be superfluous. You can add special conditioners to improve the quality of the water, but don’t think that they will quickly prepare the water. Air conditioners will bind harmful substances and heavy metals, but will not populate your aquarium with the necessary bacteria in the required amount.
    9. Switch on the filter, switch on the compressor and thermostat. Set the thermostat to the required temperature in the future.
    10. Don’t turn on the light!
    11. Do not plant plants, shellfish and fish under any circumstances.!
    Day two and three. we control the operation of the equipment.
    Fourth-seventh day. you can plant simple plants (hornwort, elodea, etc.) and invertebrates. You can’t plant fish.
    The light can be turned on for 3-5 hours a day. (If you have already planted plants, then you need)
    If the water becomes cloudy, do not take any action. the nitrogen cycle is being installed
    Seven to ten days. we plant some pioneer fish (unpretentious live-bearers, zebrafish, etc.)
    We expose the light in normal mode (usually 10-12 hours a day)
    We observe and control, we feed the fish to a minimum.
    10-15 days. wait a little more in the same mode.
    Day 15. we land the remaining population, which was assumed, but not the whole bunch at once, but in parts.
    Planting the remaining plants
    We feed the fish normally. At this point, the initial launch process can be considered complete. It remains to learn how to take care of the aquarium and enjoy the contemplation of the world created by your own hands) “

    How much water should be defended for an aquarium

    How much water needs to be defended for an aquarium?

    It depends on what kind of water. if from the tap, then 2-3 days if from the filter, then you do not need to defend. It is necessary to defend in order for the chlorine to disappear. If to replace water in aquas, then defend, if at the start of a new aquas, then you can fill it like this, you still have to stand without fish for a week.

    For topping up or changing, it is enough for the water to simply warm up and not cause a temperature shock. If I change 10-15%, I pour it from the tap! To start the aquarium, the water must stand with the equipment turned on for 5-7 days if you add “old” soil and water, and 15 days if you start from scratch at all. There are many nuances, depending on the volume of the bank, the expected population, equipment. If the water in your city is chlorinated, you need to stand for at least three days, you can heat up to 70 degrees, cool and fill. There are many options!

    Why do you need to defend water?

    The main reason for this is contaminants that can harm the inhabitants of our aquarium. After settling, sometimes solid particles appear and precipitate. Initially clear water may become cloudy after a while.

    Many aquarists leave the water for the change to breathe for several days, and in order for all the harmful suspensions to evaporate. for a week. This assumption is partially true, but it cannot guarantee the quality of the treated water.

    Before we do something, we always know why it needs to be done. By keeping the tap water outside the pipeline, we are trying to improve its performance so that it does not harm our fish. In other words, when settling water, we get rid of most of the harmful components.

    Conditionally harmful substances in water can be divided into:

    • solid (precipitates to the bottom);
    • gaseous (volatilize from water into the environment);
    • liquid (initially dissolved and remaining in water).

    The settling process can affect only solid and gaseous mixtures, and it does not affect liquid substances in any way.

    How much to defend the water for the aquarium?

    This issue has been considered many times on forums, in reference books, and it would seem that it makes no sense to discuss again how much to defend and how to fill in water during the next change. In most cases, the arguments of opponents are as follows: “the longer, the better the water”, “let all the filth disappear”, “it takes a week for everything to work out for sure”.

    At the same time, aquarists are in no hurry to justify such arguments, and water changes must be carried out regularly. Let’s consider in detail the time interval for water preparation.

    Ozone and its effect on fish

    With ozone, things are a little different. It does not have a pronounced smell, although it carries freshness. Under natural conditions, we feel it during a thunderstorm, during the operation of air conditioners (ozonizing) and laser printers. Before water is supplied to the drinking pipeline, the process of ozonation takes place, ozone molecules are unstable and quickly transform into a stable compound. oxygen. Well, oxygen is not dangerous for fish.

    Gaseous constituents of water

    This type of substance is volatilized through the surface of the water. Here you can consider the quantitative and qualitative compositions of dissolved gases in water. Gaseous substances in natural water enter into chemical reactions with other dissolved elements, due to diffusion they constantly circulate through the water mirror and are harmless and harmless to fish.

    The method of water disinfection for your area can be found at the local water utility, this information will not be superfluous. At new water treatment plants, ozone and ultraviolet purification is used, and such water can be topped up without fear (it is pointless to defend against oxygen and photons).

    The outdated chlorine cleaning method is gradually becoming a thing of the past, but it is still being used. Chlorine and its derivatives are poisons. They allow you to destroy both harmful and beneficial bacteria, as well as, depending on the concentration of large animals and even people.

    Method for removing gaseous chlorine from water

    Everyone knows the unpleasant smell of chlorine coming from freshly poured water. Water, being in a cup, after a while stops smelling, which means that the chlorine molecules have evaporated.

    Having made some observations during settling, you can see that chlorine evaporates quickly enough. It is not necessary to defend tap water for more than a day, since chlorine residues cannot affect the well-being of the fish.

    An important point is the choice of dishes. The larger the area of ​​contact of water with the environment, the faster gas exchange occurs, and chlorine is eroded. It follows from this that when the water settles in a large-diameter basin, it will become suitable for the aquarium much faster than when using a plastic bottle.

    Solid impurities

    The settling of water gives the most pronounced result in the presence of solids. In accordance with sanitary standards, they should not be in tap water.

    However, given the quality of old water pipes (rust in pipes), maintenance of pumping stations by unqualified personnel and other factors, it is impossible to exclude the presence of solid components in drinking water.

    If the water supply system is modern, made of plastic pipes and connecting elements, there will be no solid suspensions in the water.

    Lime sediment on the inner walls of the kettle indicates that you have a high carbonate hardness of water and it appears only when boiling. High rigidity is harmful only to certain types of fish. If it is necessary to lower it, then there are other ways for this. Defending such water will not give any result.

    If water is taken from a well, well or spring, then solids may be present in the form of clay particles or grains of sand that create turbidity. Such a suspension is not dangerous for aquarium inhabitants.

    True, more than one aquarist will not use such water for their fish.

    The presence of clay particles in water gives a turbidity, which settles slowly. It’s not worth messing around with cleaning. To accelerate the achievement of full transparency, floating plants with a developed root system can be planted, it perfectly collects clay particles.

    Summing up the solids in water, we can say:

    • Fill any transparent container with water and leave it for a few hours.
    • If there are impurities discussed above, then it will be noticeable in an hour (sediment or pieces of rust will appear at the bottom).
    • In the presence of visible components of solid impurities, each time before changing the water, it is necessary to settle the water (no more than 12 hours, then it is ineffective). In the absence of suspensions in the water (and they are extremely rare), settling to remove solids is impractical.
    • We take water samples once a year to control solids.

    Other gaseous impurities

    If you pour fresh water from the tap, then you can observe a certain amount of bubbles on the walls of the container. They are formed due to the presence of excess gases dissolved in water. When adding fresh water directly to the aquarium, gas compounds appear on plants, fish skin, aquarium.

    If the fish receives an excess of gases, then bubbles form in the circulatory system, which leads to blockage of blood vessels, gas embolism and, as a result, to death.

    Also, the appearance of bubbles can be caused by the method of pumping water into the water supply system. Cold water pumped into pipes under high pressure loses it abruptly when it comes out, and gases escape into the atmosphere. If you collect such water in a glass, then it will be covered in bubbles floating up the walls to the surface. She needs to be defended a little.

    With regular water changes in the aquarium, most likely there will be no bubbles. Fresh and clean water will not greatly increase the amount of gas-containing mixtures in the total volume, so there is no need to worry about the appearance of single bubbles on the fins of the fish.

    From all of the above for gas mixtures, it can be noted that:

    • the greatest danger is the presence of chlorine;
    • it makes no sense to spend more than a day;
    • in order to speed up the settling process, it is necessary to provide strong aeration in a container with water (even simple mixing with a pump will significantly reduce the time for gas mixtures to emerge);
    • to use fresh water (without settling), you can add special components to it, which are on sale in a very large amount, and after 10-15 minutes the liquid is suitable for adding to the aquarium.
