What to defend water for an aquarium

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The outdated chlorine cleaning method is gradually becoming a thing of the past, but it is still being used.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.

Is there a need to settle water?

In order for the tap water to be normalized for a change in the aquarium, it is necessary to remove all harmful components from it. solid, gaseous and liquid.

Today, defending is extremely rare. There are isolated cases of solid components in the water supply system, derivatives of chlorine water have to be removed with an air conditioner (chlorine gas is also removed at the same time), but liquid components. only with a special conditioner. Gaseous water settles for several hours, and with strong aeration, much faster.

From all of the above, it is clear that it is best to use special additives for water. The sedimentation of water does not completely remove harmful substances, and in some cases it can even be harmful (a dusty film appears, mustiness, etc.).

  • I collect the required amount of water for a change;
  • add conditioner according to the instructions;
  • I perform aeration for 15 minutes;
  • I adjust the temperature of fresh water (with air conditioning) to match the temperature of the aquarium;
  • pour in, and that’s it.

The advantages of this method of water preparation: all harmful substances are removed, there is no need to wait for the water to settle, the basins do not harm the interior of the room.

Change of water in the aquarium, what kind of water is needed for the aquarium?

Let’s talk about the questions asked in order:
In order for the chlorine to evaporate and the excess of dissolved oxygen, 24 hours will be enough for the sludge of tap water. Maximum water for the aquarium is defended for 14 days. This should be done in a bowl with a wide mouth.

Frequently asked questions: About changing the aquarium water, for example, is it possible to change the aquarium water (1/4 volume) with not settled tap water?

When changing your aquarium water, always remember that old water is always better than fresh water. In many sources, it is said about the need to change the aquarium water to fresh one weekly. Personally, I disagree with that. Since the older the aquarium water, the better the biological balance is in it. I change the aquarium water in my aquariums about once a month, and I think this is enough. For ten years of aquarium management, there have been no “complaints” from aquarium fish about this.

Drawing conclusions and summarizing the results, I will emphasize:

I also recommend that you read the article AQUARIUM WATER from which you will learn about the quality components of aquarium water and methods of balancing them at home.

Preparing the water

As already mentioned, the quality of moisture directly affects both the environment of the aquarium and the comfort level of its inhabitants, namely the fish. That is why you need to clearly understand that the water flowing in the tap is completely unsuitable for replacement without preliminary preparation.

And first of all, we check the quality of the water that flows in the tap. If it does not have an unpleasant odor and no traces of rust are visually observed, then it is allowed for filling the vessel. But here, too, you should be careful and use only cold, not hot water in order to avoid the ingress of chlorine and other conditionally harmful elements into the aquarium. So, they include:

  • Solid, precipitated to the bottom.
  • Gaseous type, with the ability to volatilize into the environment.
  • Liquid that dissolves in water and continues to remain in it.

That is why it is necessary to defend the water so as not to give the slightest chance of influencing harmful bacteria on the life of the fish in the aquarium.

Substances dissolved in water

The most dangerous constituents of water are dissolved impurities. They do not precipitate to the bottom, do not fly away into the environment and are invisible. Defending does not affect them in any way.

There are a large number of such substances, and many are not classified. It is almost impossible to say exactly what harmful substances are in tap water without a special chemical analysis. In addition, the composition of the water is not constant.

It can only be asserted that in water with chlorine antibacterial purification there is a mass of liquid chlorine components (in the greatest amount of chloramine), which remain during settling. It follows from this that in the presence of chlorine water, it is necessary to use special air conditioners that will remove not only gas chlorine, but also bind chloramines.

Ammonia, nitrites, hydrogen sulfide can be present in water in large quantities. If the dose is large, then the fish will suddenly become ill when changing the water. An aquarium with developed biofiltration (nitrifying bacteria) will transfer these harmful substances, and a newly launched one may die.

The most unstable period in terms of the composition of water in the water supply system is spring. Melting snows in fields treated with various chemicals last season form rivulets that flow into water bodies. And from them water is taken for the needs of the population.

Therefore, it is very important at this time of the year to treat the water for the change with conditioners that bind nitrites, ammonia, chlorine, metals, etc. The choice of an air conditioner depends on your capabilities and the aquarium. This market is now widely represented. It is better to consult on this issue directly from sellers.

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 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) “

Is there a need to settle water?

In order for the tap water to be normalized for a change in the aquarium, it is necessary to remove all harmful components from it. solid, gaseous and liquid.

  • pour in, and that’s it.

The advantages of this method of water preparation: all harmful substances are removed, there is no need to wait for the water to settle, the basins do not harm the interior of the room.

How to prepare water?

Freshly drawn tap water is not suitable for animal habitation. Reptiles, fish, amphibians and snails can adapt to it, but on the condition that it is infused for several days.

Fresh, domestic tap water will kill animals, since chlorine compounds are toxic to the sensitive organism of small creatures. On certain days, tap water contains different amounts of volatile substances; for testing, experts recommend turning on the shower, and observing the steam and the presence of the smell of chlorine. If the smell is pungent, you should not draw water on this day.

Regardless of the season, weather and air temperature, domestic water will be different. Be observant if you want to place animals in clean water. Infused tap water is recommended for many pets and plants, it has an acceptable acidity level: pH 7.0.

Small aquariums are filled with it, but experienced breeders warn that such water is poor in mineral components necessary for animals. Rarely use liquid from another aquarium in which there is a stable biological balance for normal life.

What does the water temperature affect??

Aquarium water at a specific temperature can stimulate spawning. This applies to increased water temperatures. However, this is not always good for fish. So, fish that spawn should not be constantly kept in such conditions. Otherwise, it will be simply impossible to get offspring from them in the future. Thus, when preparing water for the aquarium, it is better to make sure that it is one degree less than normal.

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.

  • 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?

What should be the temperature of the water in the aquarium?

The water temperature for the aquarium plays a decisive role. The health and ability of fish to reproduce depends on it. For each type of fish, completely different water temperatures are suitable. Conventionally, all the inhabitants of the aquarium can be divided into heat-loving and cold-loving.

Heat-loving fish include fish that live in water, the temperature of which is not lower than 18 degrees. Cold-loving fish are individuals that easily adapt to low temperatures. They can safely live in an aquarium, the temperature in which will not exceed 14 degrees. cold-loving fish is only possible in large and spacious aquariums.

It is noteworthy that if you put heat-loving fish in cold water, then they practically stop swimming. This suggests that significant harm has been done to their health. When preparing water for an aquarium, it is worth using tips for beginners, which can be found in special literature. So, you can choose the optimal temperature for water only after it becomes known which species of fish will live in it.

The point is that in the literature for each species of fish, an acceptable threshold for the highest and lowest temperatures is given, at which the fish will feel comfortable. In accordance with these parameters, you can select the future inhabitants of the aquarium in such a way that they all feel comfortable in the same temperature conditions. This will avoid a huge number of problems associated with m and caring for fish.

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.

How long should the procedure take at home and how to correctly determine readiness?

With a normal area of ​​contact with air, chlorine evaporates by 100% in three days, chloramine. in a few hours (up to a day).

But for peace of mind, you can use a special aquarium chlorine test. Cl2 Test. These can be drip tests or strip tests.

Experienced aquarists recommend purchasing this test primarily to test tap water. This will let you know what you have to deal with.

Probably, there is no chlorine in the water supply system, then standing up is unnecessary “dancing with tambourines”.

Spring and bottled

Although this water does not need to be defended, some hobbyists try to defend it as well. Such actions do not bring any harm to the inhabitants, as, in fact, benefit.

Bottled water can be poured into the aquarium immediately, and spring water can be poured into the aquarium immediately after the temperature of the water equals the temperature in the aquarium.

Why do you need?

Water, before entering the water supply system, passes through the filter station.

There it is disinfected, filtered and made suitable for drinking and household needs.

It is disinfected with chlorine, which is very dangerous not only for aquarium fish, but also for all living things. If you pour chlorinated water into an aquarium, you can poison the fish, but, as a rule, the chlorine in the tap water is not too high.

READ  Do-it-yourself reverse osmosis for an aquarium

Small concentrations of chlorine have no effect on fish, but even a small dose can strike beneficial bacteria colonies. And this is the most important component of the biological balance in a small underwater world, without it, water begins:

  • grow cloudy,
  • turn green,
  • everything is covered with ugly algae,
  • an unpleasant odor appears.

In the last few years, large filter stations have begun to use chloramine instead of chlorine. This is a compound of chlorine and ammonia, which is not as toxic as chlorine itself and is eroded much faster.

What funds can be used?

Many manufacturers of aquarium chemicals have made sure that the water treatment takes no more than 5 minutes.

    Tetra AquaSafe is a German product. Instantly binds chlorine, just pour the right amount into the water and mix well.

This drug cannot be overdose, it is very economical, and also contains useful vitamins and minerals for the healthy growth of plants and fish.

Of the shortcomings. you can not freeze, as well as for 0.5 l.

  • Aquayer Antitoxin K. A unique preparation that not only eliminates chlorine and chloramine, but also saturates water with potassium. the main macronutrient that plants need so much. The main advantage of this product is for 0.5 l.
  • Ricka Antichlor is a drug made in Ukraine that binds not only chlorine, but also heavy metal compounds. Thanks to this, it becomes an indispensable agent for water treatment in a shrimp pit. for 250ml.
  • In which case it is not necessary to carry out the procedure?

    You only need to defend tap water, which flows through the central highway.

    Other water does not need settling, for example:

    • Bottled;
    • Osmosis;
    • Distillate;
    • Spring;
    • Thawed.
    defend, water, aquarium

    There is no chlorine in it, so this procedure does not make sense.

    But you can let any water stand for several hours so that the temperature level with room temperature, and the fish do not have stress due to sudden temperature fluctuations.

    Features of water treatment before starting fish

    Water treatment depends on which aquarium the water will be filled into. It’s one thing when this is just the launch of the aquarium, another is a regular change in the aquarium, where there are already fish or other inhabitants.

    In the case of start-up, the water does not need to be defended at all. It is enough to leave the aquarium open. do not close the lid and turn on the aeration. The very next day there will be no chlorine in the water, the accelerated gas exchange due to aeration greatly contributes to the weathering of chloride compounds.

    When the water is being prepared for a change, it is worth taking care of the weathering of chlorine in advance:

    • Collect tap water in an enamel or plastic container. Here only one point is important. the surface area, the larger it is, the faster the chlorine disappears.
    • Further, it would be nice to find out from the water supply company exactly how the water is disinfected before starting to flow from the tap. If with the help of chlorine, then it is better to let it stand for two or three days, if with chloramine, a day will be more than enough.
    • If necessary, slightly heat the water to the temperature in the aquarium.

    How you can speed up the process?

    There are several ways to speed up the settling process:

    • Use a conventional aquarium compressor. This will speed up the gas exchange.
    • Use a “trough” pan with maximum surface area.
    • Place an aquarium filter or pump in the container, which will create ripples on the surface. The principle is the same as that of the compressor, but this method is completely silent.
    • Boiling. Chlorine is evaporated from boiling water almost instantly. This is true when 5-10 liters are required, but if we are talking about large volumes, it is better to use a different method.
    • The use of special agents that bind chlorine in water and make it safe.

    It is worth dwelling on these aquarium preparations separately.

    How to properly defend water

    There are certain rules that will help to effectively defend the water for the aquarium at home:

    • the liquid should be taken immediately into the container for settling;
    • the amount of water is taken a little more than required (some will remain in the tank along with the sediment);
    • the bucket (pan) used for this procedure must be thoroughly washed without the use of synthetic detergents;
    • the valve must be opened at full capacity to speed up the escape of gases;
    • before collecting water, it is advisable to put an aerator on the tap, so the chlorine removal process will be more effective;
    • it is advisable to choose a reservoir expanding upward;
    • you cannot close the container with a lid, otherwise there will be no point in settling;
    • a container where water settles should not be placed in the sun, in places accessible to pets.

    Why defend water

    Before starting the fish after buying or cleaning the aquarium, the water is prepared in advance by settling.

    This is a mandatory procedure for several reasons:

    • to erode gaseous substances (mainly chlorine), and solid precipitates;
    • to equalize the temperature to “room”, which is poured in the aquarium.

    Fish Tank Water Hardness Fully Explained: Don’t Kill Your Fish!

    Attention! Chlorine and some other contaminants in tap water often lead to disease in aquarium inhabitants. To prevent this from happening, the water must be settled.

    Solid

    The visible result from the settling of tap water is obtained in the presence of solid particles. According to the sanitary requirements for tap water intended for drinking, they should not be. In most Russian cities, steel water pipelines have been laid, so the presence of suspended solids from the corrosion process cannot be ruled out. There is also such a factor as the ingress of foreign particles as a result of illiterate or irresponsible maintenance of the pumping station. There are no such suspensions in the water supply system made of PVC pipes.

    If water comes from a well or well, solid particles look like a cloudy suspension of clay or sand. This is not scary for fish. To make the clay water clear, algae with a root system are placed in the aquarium, which feed on clay suspensions.

    You can talk about the degree of water hardness by looking at the teapot. Hard water is not recommended for certain types of fish, but standing water will not soften it. Aquarium care will need to be carried out using a special filtration system.

    Harmful impurities in water

    Impurities of various chemical composition are often formed as a result of preventive work carried out by water utility workers. They appear from old rusty pipes and other factors that lead to contamination of drinking water. Water settling helps to get rid of solid, gaseous and water-soluble substances.

    Soluble substances

    Chemical analysis can reveal the exact composition of the aquatic environment. Dissolved substances are the most dangerous for fish. They will not precipitate, will not volatilize when the liquid settles. Chlorinated water always contains chloramines that do not volatilize. Excess ammonia, hydrogen sulfide and nitrites also negatively affect the health of aquatic life. Special biofiltration systems help eliminate these negative factors.

    How much and how to defend water for an aquarium

    They are fond of aquarium fish at any age. In order for aquatic inhabitants to feel comfortable, it is important to know how to care for them, feed them, how long to settle the water for the aquarium, and why this procedure is needed. Quality water is required for fish just as people need good air.

    How much to defend the water for the aquarium

    Aquarists call different periods of water settling: three hours, a week, 14 days. In reality, if there is visible sediment, the water is settled for up to half a day, no longer effective. The maximum effect can be achieved within a day.

    Solid particles fall to the bottom after a few minutes. This process is observed visually. Gaseous substances begin to volatilize already at the moment of water intake. Stir to speed up chlorine removal. When it wears off, it will become clear by the absence of a characteristic smell. If the drinking water in the region is of high quality, without chlorine, from a plastic water supply, three hours is enough. During this time, the water will level out at the temperature level.

    How long it takes to settle the water also depends on the container. It is desirable that it be wide, voluminous. Then the process will go faster. When there is a lot of chlorine and other impurities, you can extend the process up to two days, no more. There is no point in standing further for the water. There is a danger that microorganisms unnecessary to fish will begin to multiply. The aquarium has its own special microflora, which helps the life of its inhabitants.

    Gaseous

    Gaseous substances leave through the surface of the water surface. In a natural reservoir, they interact with other substances, a chemical reaction takes place. The gases evaporate constantly and are not harmful to fish.

    How drinking water is disinfected in the region, you can find out in the service of the water utility. Well, if not chlorine in the old fashioned way, but ozone or ultraviolet light. Chlorinated water is extremely dangerous for the inhabitants of the underwater world. If fish are placed in such an aquatic environment, they will die from burns of gill petals.

    The pungent chlorine smell disappears over time. The wider the area of ​​the water surface, the faster. Ozone does not have a pronounced odor, its molecules are quickly converted into oxygen. But gas bubbles, when released into the bloodstream, can cause blockage of blood vessels. For this reason, tap water must be allowed to settle.

    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.

    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.

    3 Tips to Get Rid of Algae in an Aquarium (Managing Easily)

    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.

    Substances dissolved in water

    The most dangerous constituents of water are dissolved impurities. They do not precipitate to the bottom, do not fly away into the environment and are invisible. Defending does not affect them in any way.

    There are a large number of such substances, and many are not classified. It is almost impossible to say exactly what harmful substances are in tap water without a special chemical analysis. In addition, the composition of the water is not constant.

    It can only be asserted that in water with chlorine antibacterial purification there is a mass of liquid chlorine components (in the greatest amount of chloramine), which remain during settling. It follows from this that in the presence of chlorine water, it is necessary to use special air conditioners that will remove not only gas chlorine, but also bind chloramines.

    Ammonia, nitrites, hydrogen sulfide can be present in water in large quantities. If the dose is large, then the fish will suddenly become ill when changing the water.

    The most unstable period in terms of the composition of water in the water supply system is spring. Melting snows in fields treated with various chemicals last season form rivulets that flow into water bodies. And from them water is taken for the needs of the population.

    Therefore, it is very important at this time of the year to treat the water for the change with conditioners that bind nitrites, ammonia, chlorine, metals, etc. The choice of an air conditioner depends on your capabilities and the aquarium. This market is now widely represented. It is better to consult on this issue directly from sellers.

    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.

    defend, water, aquarium

    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.

    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.
