Dimmed the water in the aquarium after running fish


Muddy aquarium: from what and why the water becomes cloudy, what to do


problems of whitish, green, brown water

Turbidity of the aquarium is a frequent occurrence in new, just-launched aquariums. However, "aquarium murk" does not bypass the already established "old" reservoirs. On the Internet, a lot has been written on this issue. There are lots of articles and even talmudov about the turbid state of aquarium water. However, a significant drawback of these articles, in my opinion, is the lack of practical recommendations for eliminating turbidity and its causes. Yes, theory is good, but what to do? How to get rid of turbidity? What preparations should be used in a given situation, what actions should the aquarist take to make the aquarium beautiful and the water truly clean?
We will try to answer all these questions in this article.
So, the reasons that the aquarium water has become muddy are:
- mechanical factors;
- biological factors;
theory, reasons, ways to eliminate
Aquarium water is a closed ecosystem, where there are various artificial elements that recreate the natural conditions of fish habitat. As well as in nature, water in the aquarium may cloud due to the large number of small suspended particles that were lifted from the bottom of the aquarium, separated from the scenery, formed as a result of the livelihood of aquatic organisms (all aquatic inhabitants).
It can be said that the mechanical clouding of the aquarium is trivial, in fact, it is the dirt and debris of the aquarium, which arose as a result of laziness or proper, improper care for the aquarium.
Let's take a closer look at the reasons for this action:
Errors made when starting the aquarium. Usually the launch of the first, new, just bought aquarium, occurs in a euphoric state. A beginner in a hurry puts the aquarium in a hurry, pours in the ground there, sets the decor and fills it all with water.
Alas, such a rush, later does not well affect the appearance of the aquarium. Water appears in the water, which has not previously been washed away or washed from the scenery and the ground. This is especially true of the ground. Before you lay it on the bottom of the aquarium, it should be washed thoroughly and more than once. Otherwise, dust and small particles of soil will "spread out" throughout the aquarium.
Not the right or inappropriate care. As a result of the vital activity of fish, plants, crustaceans and other inhabitants of the aquarium, waste is generated: feces, food remains, dead organics.
If proper, regular maintenance or filtering of aquarium water is not properly set up in the aquarium, all these residues accumulate. And eventually they begin to swim throughout the reservoir. Moreover, the residues gradually decompose, which gives prerequisites for biological clouding.

The use of "not correct" decorations in the design of the aquarium.
As the decoration of the aquarium can not use bulk, soluble and coloring objects. All these objects will sooner or later be washed out or dissolved by water, which will lead not only to a violation of the aesthetic appearance, but also threatens with chemical poisoning of all living things in the aquarium.

Ways to eliminate mechanical turbidity in the aquarium

Naturally the first is a thorough cleaning of the aquarium with the replacement? aquarium water to fresh, plus siphon aquarium bottom and cleaning the walls of the aquarium. Extract all the "bad" decorations.
The second is the enhanced filtration of aquarium water. The existing filter is cleaned and washed, re-installed. Plus, another new filter is installed or a more powerful filter is bought to replace the old one.
Tip: Mechanical turbidity in the aquarium is very fine. Under the influence of any oscillation (excitement), it sweeps up and heaves. Before the general cleaning of the aquarium, it is recommended to turn off aeration and filtration in the aquarium for 2-3 hours, a little more. In the absence of generated water currents, all small particles floating in the water will gradually sink to the bottom and aquarium decorations. After that, they will be easy to collect siphon.

Preparations eliminating mechanical turbidity in an aquarium

Aquarium coal - Absorbent, perfectly coping with pollution of the aquarium. Coal is poured after cleaning the aquarium in the filter compartment and held there for two weeks. After that, a new portion of coal is removed and, if necessary, filled up.
TetraAqua CrystalWater (drug TM "Tetra") - binds small particles that are in the water and combines them into larger ones, which are then either removed through a filter, or are deposited on the bottom. Such a course of the cleaning process is guaranteed for any kind of filter.
If small particles still float in the water, these may be food remnants, with over-feeding, or particles of soil that have risen after changing water.
The product acts on both the physical and chemical levels. The first results are noticeable 2-3 hours after application. After 6-8 hours, the water becomes clean, and after 6-12 hours - crystal clear. Dosage: 100 ml per 200 l of aquarium water.
Tetra Crystal Water is recommended even with a slight clouding of the aquarium, it is very useful to use the drug before the photo session of the aquarium. In practice, the period of complete water purification can stretch for 2 days. Most likely it depends on the degree of pollution of the reservoir.

Sera aquaria clear
(similar to the previous drug, but from TM "Sulfur") - a means for removing contaminants from aquarium water, quickly, simply and reliably connects the "dregs" of any origin in aquariums.
Bound "turbidity" is removed using a filter installed in your aquarium within a few minutes. Sera Aquaria Clear - acts biologically and does not contain harmful active substances, effectively removes contaminants from the aquarium water.
theory, reasons, ways to eliminate
Aquarium water is not sterile. Even when the water visually looks perfectly clean, it contains various microorganisms and fungi that are not visible to the human eye. And this is the normal state of affairs.
In our world, everything is interconnected; everything that was invented by God is not superfluous and is needed for something. Fungi and bacteria (good or bad) in aquarium water play a crucial role for all other inhabitants of the aquarium. Fungi are involved in the decomposition of dead organics, bacteria recycle ammonia, nitrites and nitrates (aquarium poisons), etc.
Now imagine what happens if this process is disrupted? That's right, there will be murkiness! Such a violation in akvaraimistiki called "biobalance violation" or "biological equilibrium."
By the time of flow, the biobalance violation can be divided into:
Violations in the "young" - a new, just-launched aquarium;
Violations in the "old" - well-established aquarium;

dimmed water in a newly launched aquarium

In many sources on this issue it is very briefly written: "Do not worry, the clouding of your aquarium will pass by itself in 3-5 days." And the point! After reading this, the aquarium novice exhales, says "Fuv, thank God" and calms down on it.
But, with this position we can agree only partially. Yes, indeed the first 3-5 days of the newly launched aquarium will be muddy. Then whitish cloudiness, similar to fog or colostrum (sometimes with a brownish or greenish tinge) disappears by itself. But, as mentioned above, “aquarium water is not sterile,” and the absence of turbidity does not indicate that the problem has been solved.
What happens in a young aquarium? Why does the water in the aquarium grow turbid?
In short, in the aquarium there is a setting of biological balance. Namely, there is a rapid growth of bacteria, fungi and other unicellular microorganisms. At the same time, products of life of fish and other inhabitants of the reservoir accumulate in the aquarium. Not joining of the two leads to their excessiveness, which is manifested visually in the form of turbidity of water. Gradually, the process is aligned and the biological chain closes. In other words, the amount of food (dead organics, fish food residues, feces) is equal to the number of colonies of beneficial bacteria, and of fungi, which they eat and decompose into smaller “elements”.
Based on the above, we can agree that the clouding of a young aquarium is not so scary. But, it can be prevented! Or rather help the aquarium tune faster. How? We will talk about this a little later.

clouding of an established aquarium

If the clouding of a young aquarium is forgivable to an aquarist, then dregs in the old pond are his sin! Violation of the biobalance in well-established water bodies is often due to oversight, due to the lack of basic care, due to ignorance or unwillingness to know what is happening in the aquarium. The exculpatory causes of the clouding of the old aquarium include “whiteness after the treatment of fish”, that is, when aquarium chemistry and preparations were used in the aquarium. Like any "medicine" aquarium chemistry has side effects, in particular the violation of biological equilibrium.
What happens in the old aquarium? Why does the water grow cloudy in it?
And almost the same thing happens as in a young aquarium. But, if I may say so, in regressive order.
To make it even clearer to you, let's break the aquarium biological chain into links. NITROGEN CYCLE is as follows.
(remnants of dead organics, fish food, feces, etc.)
decompose under the action of bacteria in
(the strongest poison, destructive for all living things)
under the action of another group of bacteria is decomposed into
(less dangerous, but also poisons)
further decompose to
and out of the aquarium water
As you understand, this process is multistage and has its own nuances.
For those that want to study it in more detail, I recommend to go to the forum thread NITRITES AND NITRATES IN THE AQUARIUM. And now imagine what will happen in the old aquarium, if one of the links, for one reason or another, falls out? That's right - dregs! Sorry for the tautology))) Unlike the dregs in a young aquarium, the turbidity in the old aquarium not only spoils the appearance of the aquarium, but is also very dangerous. The following happens: under the influence of non-excreting poisons, the fish’s immunity weakens, their defense mechanisms weaken and become unable to resist the “harmful” - pathogenic bacteria and fungi (which are always in the water). As a result, the fish gets sick and if you do not conduct treatment in time, the fish dies. Thus, we can conclude that the violation of biological balance is the primary cause of the death of aquarium fish. In fairness, it should be said that the saturation of aquarium water with excess ammonia, nitrite and nitrate - can occur without turbidity of the aquarium water. What is even worse, because the enemy is invisible.


or how to set up biobalance
First of all, you need to make regular cleaning in the aquarium, do not overfeed the fish. Remember that only the constant and correct replacement of aquarium water to fresh water is an effective way to get rid of poisons.
ATTENTION: To replace the water in a young aquarium, in order to get rid of turbidity is not necessary. In the first month, the water in a young aquarium generally needs to be tried less often and in smaller volumes. Water should "infuse."
Drugs that eliminate the biological clouding of the aquarium - preparations setting biobalance:
Almost all aquarium brands in their arsenal have a line of products that customize the biological balance.
The essence of these drugs can be divided into those that:
- neutralize poisons (nitrites and nitrates);
- promote the growth of colonies of beneficial denitrifying bacteria or are a ready concentrate of these bacteria.
To achieve the maximum effect, you should use these drugs in a complex. Especially with a flash of nitrite and nitrate.
Preparations that neutralize nitrites and nitrates Zeolite is an ion exchanger, in fact, as well as aquarium coal is an absorbent. But, unlike coal, which is not able to “tighten” nitrites and nitrates, zeolite copes with it perfectly. Zeolite is used not only in aquarism, it is widely used in other areas of human life. Therefore, it can even be bought by weight.
Zeolites are a large group of similar in composition and properties of minerals, aqueous aluminosilicates of calcium and sodium from the subclass of frame silicates, with glass or pearlescent gloss, known for their ability to give and reabsorb water, depending on temperature and humidity. Another important property of zeolites is the ability to ion exchange - they are able to selectively release and reabsorb various substances, as well as exchange cations.
Aquarium preparations containing zeolite.

Fluval zeo-carb - a filler for filters zeolite + absorbent carbon.
This is a combination of Fluval activated carbon and Fluval Ammonia Remover. Working together, these highly effective means of active filtration, which eliminate pollution, odors and color, and at the same time, remove toxic ammonia:
- Protects an aquarium from toxic ammonia.
- At the same time, coal adsorbs waste materials, dyes and drugs from water.
- Reduces the phosphate content in water.
The combination of the two products frees up space in your filter for other types of filtering.
Aquael ZeoMAX Plus - zeolite in the form of small crumb, removes ammonia and phosphates, stabilizes pH.
Due to its chemical structure, it provides excellent absorption of organic pollutants, nitrogenous compounds and phosphates that are toxic to fish, which are a consequence of the metabolism of aquarium inhabitants.
Zeolite should not be left in the filter for more than one month.
For more information about the advantages and disadvantages of zeolite, see the forum thread "Nitrites and nitrates", namely HERE.
The drug acting at the chemical level.

Sera toxivec - a drug that at the chemical level instantly eliminates NO2NO3. Since this is chemistry, it is recommended to use it as a preventive measure and once.
Immediately removes hazardous contaminants, life-threatening fish and filter bacteria, from aquarium water. Equal effectiveness against different types of pollutants makes this tool especially valuable.
Sera Toxivec instantly eliminates ammonia / ammonia and nitrites. Because of this, it prevents their transition into nitrates and helps prevent the growth of irritating algae.
In addition, Sera Тoxivec eliminates aggressive chlorine from tap water. Also effective as a disinfectant disinfectant and medication remover.
At the same time, it is capable of even more: it binds toxic heavy metals such as copper, zinc, lead, and even mercury. Therefore, these pollutants can not harm the fish and beneficial bacteria in the biofilter. Due to this, the frequency of water changes can be reduced.
If necessary, for example, with particularly high levels of contamination, an increase in the applied dose of the agent is allowed. Repeated depositing is allowed in one or two hours.
Drugs that promote the growth of beneficial colonies
bacteria or are ready concentrate bacteria
Tetra Bactozym - This conditioner, accelerating the process of stabilization of biological equilibrium, in the filter and aquarium. Suitable for fresh and sea water.
Tetra Bactozym accelerates the conversion of nitrites to nitrates and contains a concentrate of enzymes and substances that contribute to the development of beneficial aquarium microflora. It makes water crystal clear and provides enzymatic decomposition of dissolved organics. The use of an air conditioner reduces the damage done to the beneficial microflora when changing water and washing the filters, and restores microorganisms that are weakened or damaged by the use of medicines.
We draw your attention to the fact that biostarters contain various types of cultures of bacteria and enzymes. Too high or low temperatures reduce their effectiveness.
Tetra NitranMinus Perls (granules) - for reliable reduction of nitrate in water. The drug eliminates the nutritional element necessary for the development of algae, which allows for a long time to improve water quality, reducing, thereby, the need for care of the aquarium.
- lowering the level of nitrates by 12 months by biological means.
- significantly algae growth is restrained.
- just buried in the ground.
Tetra NitrateMinus (liquid conditioner) - biological reduction of nitrates, calculated for 12 months. Improves water quality. Interferes with formation and growth of seaweed (duckweed). Designed for all types of marine and freshwater aquariums.
Convenient dosing: 2.5 ml of new liquid NitrateMinus for every 10 liters of water, once a week.
Like NitrateMinus in granules (Pearls), liquid NitrateMinus facilitates the processing of nitrates into nitrogen and lowers carbonate hardness. A decrease in nitrates by 60 mg / l leads to an increase in carbonate hardness of approximately 3 KH. При регулярном использовании препарата после замены воды, стабилизируется показатель воды pH и снижается риск падения кислотности .
Полная совместимость, NitrateMinus основан на биологических процессах в аквариуме и полностью безопасен для рыб. Он прекрасно сочетается с TetraAqua EasyBalance и другими продуктами Tetra.
Sera bio nitrivec (Sera био нитривек) - A preparation for quick launch of the aquarium. Special blend of various high-quality cleansing bacteria for aquariums. Sera nitrivek prevents the accumulation of ammonium and nitrite. The use of Sera nitrivek makes it possible to place the fish in the newly created aquarium already 24 hours after application. When entering the water bacteria
begin to act immediately. The resulting effect is stored in
For a long time, giving a crystal water aquarium water.
There are other drugs of identical orientation. I recommend sharing Tetra Bactozym and Tetra NitranMinus Perls.
And when using NO2NO3 flashes, use zeolite.

How else can you achieve a “good biobalance”?

- Biological equilibrium is more stable if live aquarium plants are present in the aquarium. Plants partially absorb the decay elements of living organics and thereby reduce their concentration. The more aquarium plants, the better. I recommend to read the article. AQUARIUM PLANTS ALL FOR BEGINNERS.
- Aquarium snails and fish "orderlies" will help you in cleaning the aquarium. "Squad" of the same coil snails copes with dying leaves and organic matter. Fish nurses also help in this matter. Most of the aquarium catfish can be attributed to them: corridors, antsistrusy, girinoheiliusy, aquatic sequences, thoracacums and many others.
- It is advisable to use multistage filtration of aquarium water. And also use other methods to improve water quality, for example, phyto filtration.

Causes of water turbidity and how to deal with it

Muddy water in an aquarium is a common phenomenon that almost every aquarist has encountered. Sometimes the causes of the problem are found quickly, and sometimes it takes a long time to figure out why the water has become cloudy. How to deal with the formation of turbidity, what is recommended to do and what is not?

When does water appear in the water?

The causes of muddy water in an aquarium can be varied, and it is not as easy to deal with them as it seems at first glance.

  1. Turbidity can occur due to swimming in the pond of small particles of algae, solid organics and cyanobacteria. There is another unobtrusive reason - poor washing of the aquarium soil and inaccurate pouring water from a clean tank. This type of turbidity does not threaten the water and the fish, you can do nothing with it. After some time, the muddy part of the water will settle, or seep into the filter, remaining there. The formation of turbidity can provoke fish who love to plow the ground, but these actions for the reservoir are completely harmless.

  1. Turbid water in an aquarium can be caused by cichlids, goldfish and tail finch fish - their active movement in a reservoir is the cause of the resulting turbidity. If a filter is not installed in the tank, it will be difficult to clean the water.
  2. Often, muddy water appears after the first start of the aquarium, after the fresh water inlet. Nothing to do, in a day or two the sediment will fall to the ground and disappear. The mistake of novice aquarists is a partial or complete renewal of water, which is considered a gross error. When adding new water to a newly launched aquarium, the bacteria will become even more! If the aquarium is small, you can install a sponge filter that quickly cleans the pond.

Watch the video about the device and the operation of the internal filter.

  1. Malicious bacteria in an aquarium can also be causes of turbidity. When the water becomes green, then it's time to draw conclusions - this is an unnatural color. Muddy and green water is formed due to overcrowding of the aquarium with fish or plants. That is, the aquarium fluid passes through the filter, but is not cleaned. The abundance of metabolic products provokes the formation of putrefactive microorganisms, ciliates and other unicellular. If ciliates are beneficial, the bacteria can harm the plants - they will start to rot. In order not to be surprised why fish and plants often get sick - watch the aquarium clean and tidy.

  1. Why still breed single-celled? Because you do not have time to clean the tank after heavy feeding. For aquarism it is better to underfeed than to feed. This rule will protect the fish from problems. After overfeeding again the water got cloudy - what to do? Arrange a pet unloading diet for a couple of days, the bacteria will die out, the water biobalance will be restored.

  1. Incorrectly installed decoration. Snags, plastic materials of poor quality dissolve in water, forming a muddy shade. If the scenery is new wooden, but untreated - they can be boiled or infused in salt solution. Plastic snags should be replaced by new ones.
  2. In the old, stagnant nursery with fish sediment is formed due to "whiteness after fish treatment", this is when drugs and purification chemistry for aquarium glass were used in the pond. Such substances have a number of side effects, they disrupt the biological equilibrium, neutralizing the favorable microflora.

How to overcome turbidity in water?

Now we know the reasons why the water grows cloudy in the aquarium, and what to do in each case. However, there are general rules, without which it is impossible to completely eliminate the problem.

  1. Siphonte the soil in the aquarium. Open the filter, rinse and clean. Then add activated carbon to it - this needs to be done to absorb harmful substances. It is forbidden to make a complete replacement of water and washing the aquarium soil, otherwise the beneficial bacteria will die out and will not be able to process rot and algae.

See how to siphon the soil in the aquarium.

  1. In some cases, it is necessary to do an intensive aeration of the aquarium - when there are a lot of fish feed residues and a fasting day is not enough. Oxygen will quickly remove excess organics.
  2. If an unpleasant smell disappears in an aquarium, it means that the struggle with mist is over successfully. Also for elimination of bacterial turbidity it is possible to use elodeya, having landed it superficially in a ground.

Dregs in the water: types

The color of turbidity will tell about the sources of its formation:

  • The water color is greenish - single-celled algae reproduce;
  • Brown water - peat, humic and tannins, poorly processed snags;
  • Milky white color - unicellular bacteria begin to multiply;
  • The color of the water coincides with the color of the soil or of a stone recently laid on it, which means that the soil was plowed by fish, or the stone turned out to be fragile.

Drugs that prevent the appearance of turbid sediment

  1. Aquarium coal is absorbent, which is added after cleaning the tank to the filter for a period of 2 weeks. After extraction, you can fill in a new batch there.

  1. Tetra Aqua CrystalWater is a tool that binds small particles of dirt into one, after which they can be removed or passed through a filter. After 8-12 hours the reservoir will be crystal clear. Dosage - 100 ml per 200 liters of water.
  2. Sera Aquaria Clear - also binds sediment particles, passing it through the filter. During the day, dirt can be removed from the cassette. The drug does not contain harmful substances.
  • Before adding sorbents to water, it is better to move the fish to another container.


In order to avoid turbid water, it is necessary to control the level of nitrates, nitrites and ammonia. They stand out as a result of the vital activity of fish, plants and improper care of the water body. Therefore, fish should be settled in the tank, the size of which corresponds to its volume. Proper feeding of pets, timely cleaning of the products of their vital activity, removal of rotten plants will settle the water balance. If there is no mechanical or biological filter in the aquarium, replace 30% of the water weekly with fresh and sedimented. Do not add water from the pipeline with the smell of chlorine or boiled.

Why does the water grow turbid in the aquarium?

Muddy water in the aquarium This is one of the most common problems that even experienced aquarists face. The reason for the violation of biological equilibrium can be a bacterial outbreak, improper feeding of fish, replacement of water in the aquarium and other factors. In some cases, it is enough to eliminate the cause, and after a few days the balance will be restored. But sometimes the turbidity of the water in the aquarium can lead to the death of fish and plants. In any case, first of all it is necessary to establish why water grows turbid or blooms in the aquarium. And, only on the basis of the causes of violations, will it be possible to take any action.

Why does the water grow turbid in the aquarium?

When starting the aquarium for several days, there is a bacterial outbreak caused by excessive multiplication of single-celled organisms. Therefore, it is not recommended to colonize the fish immediately after launch. It is necessary to wait until the balance is established and the water becomes transparent. At the same time, changing water is also not worth it. A change of water will only cause it to become cloudy again. Usually, fish are settled in 5-7 days, and to speed up the process of restoring biological balance, it is recommended to add water from the old aquarium.

Turbid water in the aquarium can be the result of overfeeding the fish. If the food is not eaten completely, and settles at the bottom, the water will quickly deteriorate.

Also, muddy water in the aquarium may indicate poor filtration. With a large number of fish, you need to think very well about the water purification system, otherwise very soon the fish will start poisoning with decay products, which can cause the death of the inhabitants of the aquarium.

Why is the water in the aquarium green?

The flowering of water is due to the rapid growth of microscopic algae. This may be caused by an excess of light or accumulation of organic matter at the bottom. With a lack of lighting algae begin to rot and turn brown. If the water in the aquarium is clouded and smells, then the cause may be the reproduction of blue-green algae.

What to do if in the aquarium muddy water?

First of all, of course, you need to eliminate the cause of turbidity. If the problem lies in overpopulation of the aquarium, then you need to either increase water filtration or reduce the number of fish. If at the bottom of accumulated remnants of food, you need to reduce portions, and you can also settle the bottom fish that eat food settled on the ground. When flowering you need to darken the aquarium, if there is an excess of lighting, or vice versa - to establish a more powerful lighting system with a lack of light. To prevent excessive algae growth, it is recommended to make fish or snails that eat excess vegetation. It is also worth paying attention to the filtering system. The presence of good filters is a prerequisite for the maintenance of the aquarium and the preservation of biological equilibrium. Sometimes it is recommended to add special additives to the water, but most aquarists do not support this method of restoring balance. In any case, it is necessary to understand that the living water in an aquarium is the result of the interaction of many living beings, therefore, time and certain conditions are necessary to restore balance. Incorrect actions can lead to even greater disruption, so the main task is to create conditions for stabilizing the balance.

How often do I need to change the water in the aquarium?

Proper replacement of water in an aquarium plays an important role in maintaining balance. A common mistake is to replace too often or replace large amounts of water. With a small litrazh such errors can result in the death of the fish. Before you change the water in the aquarium, you need to check the water quality, acidity and temperature. With a large volume, it will take about 2 days to restore balance; with a small volume, water needs change very carefully. After the launch of the aquarium water can not be changed for 2-3 months, until equilibrium is established. Subsequently, every 15-30 days replace up to 1/5 of the total volume. With a good filtration system and a small amount of fish, water is changed less frequently and to a lesser extent. If you replace more than half of the water in the aquarium, then the whole formed environment, including fish, may die.

In order to avoid problems, it is worth taking care of the proper equipment, starting and settling the aquarium from the very beginning. If you follow all the rules, it will not be difficult to achieve and maintain biological balance, and caring for an aquarium will not cause problems.

The water in the aquarium dimmed on the second day

Irina Gridina

The water with which you fill the aquarium should be infused during the day, at room temperature, only then you can settle there. And the light in the aquarium should be only artificial, you need to avoid direct sunlight. You can not put dirty hands in the aquarium. Maybe this is the problem. Or maybe such a variety of aqua world in your aquarium is not acceptable.

Turanga Leela

First, you need patience. Give someone a fish for a while, Drain. Fill with water again, let it stand for at least a week. The water will grow cloudy on the second day, this is normal. This sets the balance in the aquarium. But after a week already plant fish. And this liquid, Aquaseife, pour into the toilet.)) This is of course a joke)) But do not experiment on the fish, take pity on them.

Marusya Rennes

I hope you prepared the water poured.
1. Try to reduce the lighting.
2. Look at what the displacement of the filter is calculated.
For the future: write what volume, location, ground.
By the way: I once threw a new, unwashed ground - I had a picture similar to yours.

Vitaly Statsenko

always do as you like 10 years kept the fish poured water directly from the tap did not use chemistry except for chlorine I always lowered the plants for a couple of seconds after the market after the market so that your water itself will soon become clean but about dirty hands it is nonsense they are very good washed in the aquarium and the fish do not die from this and the water nemutneet frogs better to remove and everything is normal. no longer plant a small aquarium grass throw out little benefit from it


People, what do you advise some ... nude? Bacterial outbreak, hence the dregs, when you start a new aquarium, this can not be avoided, a balance will be established in a few days, and everything will pass by itself, the water will be clarified! The filter can not be turned off, it would be better to run the fish one by one - two, but not all at once! But what now is done, done! And henceforth! AquaSafe and other shit place in the toilet, and not in the aquarium!

Natalia A.

A bacterial outbreak at the start is a NORMAL phenomenon, of course, we hurried with the fish and your aquasafe is humorous, but essentially to darken, intensify the purge and filtration, do not feed the fish for a couple of days, everything needs to be changed, and WASHING NOTHING IS NECESSARY!

Oksana Stepanova

Hello friends. Today we will talk about such a moment as muddy water in an aquarium. This phenomenon is very common and many beginning aquarists are afraid of it and do not know the reasons for this phenomenon and how to actually fight it. In today's article I will try to shed light on this mystery and I hope that newcomers after reading this article will be as they say "in all weapons." And so, let's start to understand.
Turbid water in an aquarium can become for a variety of reasons, and sometimes it is not very easy to deal with this negative point. The main reason for which the water in the aquarium grows turbid is that small particles of solids, algae or bacteria float in it. There is still an innocuous moment of muddy water - this is if you have poorly washed the aquarium soil and have not carefully poured in some water after cleaning the jars. Here such turbidity does not represent any harmful consequences for your aquarium and after a certain time the cloudiness will partially settle, and partially fall into the filter and remain there. They can also raise the dregs of fish, crawling in the ground.
With the turbidity of the water in the aquarium, owners of aquariums often encounter voile tails, cichlids and goldfish, which constantly dig in the ground, plus aquariums in which there is no filter. Turbid water appears after the start of the aquarium, when you fill it with fresh water. Do not do anything with it, it is disgusting rose from the ground, it literally settles within 24 hours. A very common mistake of newbies - they, as they see muddy water after the start of the can, immediately begin to change it and refill it fresh and the process repeats. In the absence of a filter in aqua, the water starts to deteriorate rapidly, and it deteriorates more strongly in aquariums of small volume. Sponge filters will come to the aid of the aquarist.
Muddy water in the aquarium
Extremely worse impact on the aquarium has a murk of bacterial origin. If the aquarium is overpopulated and there are some aquarium plants, the water may become cloudy. Water is essentially only passed by the filter but not filtered. In this case, there will be a lot of metabolic products in the water, which will serve as an excellent food for bacteria and all kinds of single-celled. Also, the water may become turbid in the aquarium due to ciliates and various putrefactive bacteria that are abundantly distributed in such water. These reptiles are equally harmful to plants and fish. The main reason for the development of these bacteria is an oversupply of organic matter in the aquarium.

Irina Semenyuk

I defended the water for a week before running the fish on the pebbles, too, thoroughly washed them, and the water was already cloudy. can this all because of the feed? I was recommended plate feed who knows he is normal?

Why did the water in the aquarium dim after running the fish?

Andrey Kovalenko

I understand that you filled the water in the aquarium on the same day? If yes, then the water is clouded from the breeding of bacteria and if you moderately feed the fish (very moderately !!!), then in a couple of days the water will become clear, if you make a mistake in feeding, then the fish may not survive. Do not change the water yet.I hope the fish you have there is not too much and there are living plants.


When starting the water, it may become cloudy - the balance will be restored)) Wait a few days, everything should be restored ... I have no plants in one aqua)) But ... there is a filter and a compressor)) two different


everything is normal, just do not change the water. the aquarium is zero, there are no bacteria in the water, and therefore there is no balance. it will take several days and the water will again become clear. don't change the main water, otherwise it will always be muddy

After replacing the water in the aquarium, 100% dimmed after 14 days why and how to fight?

Water turbidity can occur for various reasons; to deal with these phenomena is not always easy. In the most benign case, the water becomes cloudy due to the fine particles of a pound suspended in it, for example, after carelessly pouring water into the aquarium. Such clouding does not have any unpleasant consequences and after a while disappears by itself when the turbidity settles to the bottom.
The water in the aquarium becomes cloudy with the appearance of a large number of putrefactive bacteria in it, which are very harmful not only for fish, but also for aquatic plants. The reason for the appearance of such bacteria is improper feeding and overly dense fish landing in the aquarium. For good filtration of water, coarse-grained, clean-washed river sand should be poured to the bottom of the aquarium, preferably in a dark color, 4-5 cm layer. Do not carry out a complete change of water in the aquarium, you only need to clean it periodically with a rubber (glass) tube dirt from the bottom and add fresh water of the same temperature. A properly equipped and well-contained aquarium can last for years without changing water. It establishes the so-called biological equilibrium. The norm of landing fish - 2 3 pieces the size of 3-5 cm for 1-3 liters of water.
Major troubles arise from improper feeding. First of all, dry feed should be abandoned: dry fish feed is rather bad, and water deteriorates very quickly. If you have to resort to dry food, then it should be given little by little and it should be watched that all food would be eaten immediately. Great help here are snails, willingly eating the remnants of food. A properly prepared ration must necessarily include live food. One of the best feed is the bloodworm. It should be given on the basis of the norm of 3-5 worms per day for each small fish of small size.
It is necessary to ensure that any food is eaten in 10-15 minutes: the constant presence of food at the bottom of the aquarium is unacceptable. Worm tubers are also good food, however they should be washed very thoroughly in clean water from dirt before giving to the fish. Cortera serves as an excellent food - a transparent floating larva of one of the mosquito species. She does not dig in the ground, she lives in the aquarium for a long time and is very eagerly eaten by fish. At home, enkhitrei worms are easily divorced in a small box with earth. Daphnids and cyclops serve as good food, which you can catch yourself in any kind of puddle with the help of a net from a dense nylon.
With a known experience and skill, you can feed the fish with raw raw meat, but this should be done with the greatest caution: the water from the meat spoils very quickly. If the water has become cloudy, then it is necessary to stop feeding for a few days: the bacteria will die, and the fish will not be harmed. And there is another rule: it is better not to feed than to feed. Under these conditions, the water in the aquarium will be transparent.
Many novice aquarists when cleaning a small capacity aquarium are completely replacing water in it, replanting fish and removing plants. At the same time fish are injured and plants spoil. Often you can hear the full disappointment statement: "The more often I change the water, the more it becomes cloudy." This is true.
In the newly equipped aquarium in the first few days the water may be muddy due to the strong reproduction of single-celled organisms. After the aquarium is prepared and filled with water, you should be patient and not be sewn up with its stocking. As a rule, on the second or third day, the water in the aquarium becomes muddy, as if a few drops of milk dripped into it, because after a complete replacement of water, microorganisms usually grow rapidly after a while; plants, and the water becomes cloudy, not from the weed particles, but from the infusion, the so-called "infusor turbidity" arises.
The rapid reproduction of bacteria can manifest itself in your aquarium every time you replace a large amount of water, and also in cases where you forget to remove the remnants of non-eaten feed from the aquarium in time ...


The water becomes cloudy somewhere on the third day, since a new microflora is formed, maybe later. Did you have any separated water, or did you immediately fill it up? How well did you do the water change. Fish in this case can not immediately run. There are all sorts of nuances.


Maybe you have a small aquarium 10-20l, you have a lot of problems with it and often (once every 1-2 weeks) you need to change the water, the bigger the aquarium, the better, they completely change the water once a year, and during the year they simply drain it Of course, not completely until the end, without replanting the fish, wipe the walls and pour new ones, and new fish should be held in a special solution for prevention before they are planted in the general aquarium. Zha and sunlight is bad for water, it blooms, everything was explained to you in detail, good luck

Why in the aquarium muddy water, after the settlement of fish?! ((2 weeks have passed))

Yeah, a lot of answers, probably from those who never had a fish. To start a simple aquarium, fish and food, this is very small. Look a bit on the Internet and ask about all that is important for the maintenance of the fish. First, 1 cm of fish requires 1 liter of water. If you assume only 10 liter aquarium, then it should be no more than 5 fish 2 cm in length. The aquarium requires a special filter that purifies the water and at the same time supplies oxygen. Aquariums do not like the direct rays of the sun. From this, the water also becomes turbid and very quickly, especially in the summer. Feed the fish means to know the measure. Fish are insatiable, but this does not mean that they are hungry. Do not feed them out of love like piglets. Especially, when the family, everyone tries to throw a tiny bit at them, which could be fatal. This is not a toy! Set the rules if you do not want the water to become cloudy and the fish die! Algae are also important. They are a place for fish where they can “hide”, but also “pinch”. There are fish that clean the aquarium, or special snails. It seems like I have not forgotten anything, there will be questions, ask! I will answer with pleasure and if it is in my competence :-)


There is a process of setting the biobalance. Because the fish brought their microflora to the aquarium. This process can take up to 2 weeks. Have patience, and if at the same time fish are active, outwardly healthy and they have an appetite, then there is no reason for panic.

The aquarium needs to be launched, and this is a long process. At first, the filter of day 3 simply works, so that the water is enriched with oxygen. Then plant bushes, let a couple of snails. Melania also buy pieces 5, this is a snail ground. Then you start 1-2 gupeshki, these are starting fishes. Let them live alone for a month until microflora is formed. Then you can only let the fish you want to keep, and then a week, one at a time, no more!
If you do not start the aquarium, just pour water, turn on the filter and settle the fish, then soon they will simply be poisoned by their own feces, rotting food remnants ... Because there are no bacteria to decompose these things yet. The water will cloud, the fish will hang under the surface and breathe convulsively. Or vice versa zayagut to the bottom.
In general, what you need to do now is to change half the water, buy special pills at the pet store, or whatever they are with special bacteria, there are some. Maybe the fish will be saved.
I wish you success!
