Why does the water quickly grow turbid?
Muddy water in an aquarium with fish is perhaps the most common problem that concerns both beginners and experienced aquarists. Through trial and error, we have to figure out why muddy water appeared so quickly. The causes of this phenomenon can be different, ranging from a bacterial outbreak, improper feeding and irregular water renewal. A number of factors may also be the source of this problem. When the elimination or elimination of the causative agent of water turbidity in an aquarium occurs quickly, then the biological balance in the water is fully restored.
Sometimes this trouble provokes the death of fish, plants and invisible microorganisms. The first thing to do is to find out why the water becomes cloudy quickly. The second is to gradually eliminate the shortcomings.
Causes of Aquarium Water Turbidity
Why is the aquarium water quickly dimmed if the tank is equipped with a filter? The main problem is that on the very first day of the launch of the aquarium there is no holistic and permanent biological environment. The so-called "bacterial explosion" is caused by an active increase in the number of unicellular microorganisms that are constantly multiplying. In this case, the fish should not be settled, it is better to do it on another day. When microflora equilibrates in the tank, then the water will become crystal clear. Nothing serious needs to be done - this sediment will pass by itself. If you decide to change the water - it will again become muddy and unfit for life.
For 4-7 days the aquatic environment is fully restored, you can run plants and fish into it. To speed up the process, you can add water after the old aquarium with "residential" water.
Another common problem with the rapid turbidity of water in an aquarium is poor filtration of the reservoir. It should be well thought out system of purification, and this should be done quickly, until the young fish and did not have time to get used to a new house. A bad filter does not allow bits of dirt, feces, food debris, provoking the formation of decomposition products. Such rotten water constantly stinks and can cause diseases.
Watch a video about filtering water in an aquarium.
Why still water quickly becomes cloudy? If it has become an unpleasant green color, dimmed in a short time - it means that microscopic blue-green algae develop in it, which lead to the flowering of the reservoir. With good development of organic and strong light, they make themselves felt on the fifth day. When the light is not enough, cyanobacteria will acquire a brown color and begin to rot. Green color of the liquid with muddy, unpleasant smell - signs of growth of blue-green algae.
Aquarium water turbidity: action
If frequent water changes, the growth of bacteria and algae provoked the appearance of muddy water in the aquarium, some steps should be taken to eliminate the problem.
- If your aquarium is overpopulated, place the fish in different tanks, where they would be comfortable and spacious.
- If there is an excess of light, shade the aquarium by setting it in a secluded corner where strong lighting does not go.
- If the water becomes cloudy the next day after the first feeding, make a bottom siphon and feed the fish in small portions.
- Settle snails and fish in an aquarium that eat leftover food, clean glass and water in a tank. After a few days, the water will become free of dirt, and will not require additional replacement.
Wrong settlement of fish as a reason for the rapid turbidity of water
Why 2-3 days after the settlement of fish water became muddy? The fact is that for every one liter of water in the tank it is required to settle only one medium fish. If you run more pets, there will be problems with the pollution of the "house". Some fish plow the ground, and if there are many such individuals, it will turn into an underwater hurricane. Immediately move the fish in different aquariums, provide enough space for them. It is also important that they have enough oxygen, shelters and plants. In poor water oxygen to the fish can get sick.
In the aquarium with proper care and the right equipment, the water on the second day will not deteriorate. After running the fish, make sure that it adapts to the new environment. For 3 liters of water it is necessary to settle the fish size of 3-5 cm.
If the water is cloudy, you can use drugs that purify water from turbidity and dirt. After using them, water changes in the aquarium are not required for a few more days. They connect all the small particles that spoil the water until they fall into the filter. The next day, the entire bacterial cloud, small algae settle on the filter sponge, after which they can be removed.
These are the drugs: JBL Clearol, JBL Clynol, Seachem Clarity, Sera Aquaria Clear.

How to change the aquarium water?
Full replacement of water is required only in the rarest cases, for example, with general quarantine or water poisoning. Why not do this procedure often? Because the day after the complete substitution, you will notice how the water turned cloudy again. A significant loss of its volume is stress for all inhabitants of the reservoir. Even during the death of some fish do not replace the water. But there are a number of recommendations, after studying which it is possible to understand why substitutions are necessary.
- Substitutions are necessary after the introduction of pathogenic microorganisms;
- Replacements are required after visible flowering of the reservoir;
- Urgent water changes are necessary when a fungal mucus is detected;
- Refresh water is required due to severe soil contamination.
You can add water to the tank as it evaporates, but not more than 20-30% of the total volume. It is best to update 1/5 of the aquarium once a week. After the procedure, the biocenosis will recover in 2 days. With the replacement of water cleaned the glass from plaque, remove debris from the bottom, clean snags and decorations.
It is better to plan a water change for both small and large reservoirs in advance. Type in a glass tank water from the tap, and leave it for a few days, covered with gauze. Chlorine and gas will evaporate, the liquid will be safe for fish. And it should be remembered that in the first week of operation of the aquarium the water is not changed until an ecosystem is formed in it.

Tip 1: Why the water becomes cloudy in the aquarium
Muddy water in an aquarium is a common problem that even experienced aquarists sometimes face. It can be fatal for your fish. To avoid this, you need to understand the causes of this trouble and eliminate them.
The question "opened a pet shop. Business is not going. What to do?" - 2 answers
From what the water in the aquarium muddy
An aquarium is a microworld where organisms appear and die. It consists of a fine interconnection of fish, plants and bacteria.
When you create a new aquarium in a few days there is a huge number of bacteria, excessively breeding in water. This leads to its turbidity. This process is quite normal and natural. Before you run the fish in the aquarium with new water, you just need to wait a few days until it clears itself. Due to lack of food, most bacteria will become extinct, and the biological balance of water will normalize. To change the water in this case is strictly prohibited, because it also becomes cloudy. It is best to add some water from the old aquarium, where the balance has long been established. If this is not available, nothing terrible, the balance in the water itself is settled, it just takes more time for this.
Another cause of muddy water can be overfeeding fish. Excess feed, which your pets do not have time to eat, sink to the bottom and begin to rot. As a result, the water begins to deteriorate. In such an environment, the inhabitants of the aquarium can not feel good, and their long stay in bad water will destroy.
When a large number of fish in the aquarium and, at the same time, poor filtration of water, there is its turbidity. The inhabitants of such an environment will certainly begin to poison the body with decay products, which will lead to their death.
The cause of muddy water can be algae. There is a certain species that, if overproduced, leads to a turbid environment in the aquarium and at the same time emits an unpleasant odor. Another problem may be excessive light or accumulation of excess organic matter at the bottom, which stimulates the rapid growth of microscopic algae, and as a result water will bloom. It becomes opaque with a greenish tinge. With a lack of light, the plants in the aquarium will turn brown and begin to rot, which will ruin the habitat of the fish and harm their health.
What to do with muddy water in the aquarium
To deal with muddy water is not difficult, the main thing is to understand the causes of turbidity and follow certain rules in the future.
First you need to determine the cause of the turbidity of the water. If it consists in overpopulation of the aquarium, then it is necessary to strengthen the filtering or move some fish to another place. If the reason is the accumulation of excess feed on the bottom, then you need to reduce the dose of food or purchase bottom fish that will eat up the settled food. If there is a problem with lighting, you need to darken the aquarium or enhance the light. To prevent the rapid growth of algae, it is recommended to start fish or snails that eat plants. In order to maintain biological balance in an aquarium, it is imperative to have a good filter that matches the size of the water tank. You need to understand that in the aquarium the water is alive, and to maintain balance you need to maintain certain conditions. It does not recommend the use of chemicals, they can lead to even greater environmental disturbance and will require a longer recovery.
In maintaining balance in water, its change plays an important role. After launching a new aquarium, it is not necessary to change the water for 2-3 months until the balance is improved. In the future, the water should be replaced 1-2 times a month. At the same time merging only 1/5 of the total volume of the aquarium and adding as many new ones. If you change more than half, then the habitat is disturbed, which will lead to the death of the fish. In small aquariums, water can be replaced less frequently, provided there is a good filter.
Tip 2: Why the water becomes cloudy
A properly equipped and properly maintained aquarium in which biological balance is maintained may not require changing water for a long time. The problem of water turbidity often occurs in novice aquarists, who believe that caring for fish is only in abundant and timely feeding.
1. The water becomes turbid due to small particles of soil that have been washed out of it, which are washed out during the careless filling of the aquarium with water. After they settle to the bottom, the water will again become clear. Do not replace water completely when it is not required. Using a rubber or glass tube, periodically remove dirt accumulating on the bottom and add the required amount of fresh water, ensuring that its temperature coincides with the water in the aquarium.
2. Water may also become turbid in a new, newly equipped aquarium, due to the reproduction of single-celled organisms. This phenomenon is called "infusorial turbidity". Do not rush to settle an aquarium prepared and filled with water, wait a few days. Another harmless cause of turbidity - loosening of the soil by fish digging in it - is easily eliminated by placing a layer of thoroughly washed sand on the bottom.
3. The turbidity of the water can be caused by the appearance of a large number of putrefactive bacteria that are very harmful to fish and plants due to too high a concentration of fish in the aquarium or improper feeding. Follow one of the basic rules of aquarism: "It is better to underfeed than overfeed."
4. If you forget to clean up the remnants of food and rotting plants in time, this can also provoke a rapid reproduction of bacteria. In addition, turbidity can be caused by poor filtration and blowing of water, as a result of which accumulation of metabolic products occurs in the aquarium, which serve as an ideal medium for mass reproduction and feeding of bacteria. To avoid such consequences, squander excess fish and improve the filtration system.
Refuse dry feeds or give them a little and watch them to be eaten as soon as possible. Place in the aquarium snails, which are willing to clean up edible remains.
If the water dimmed after starting the aquarium
After the first start of the aquarium, sometimes the water becomes cloudy, thus acquiring an uncharacteristic color. In itself, turbidity is not a terrible phenomenon, it is a signal that something is wrong in the water and there is a need to do preventive procedures to eliminate the problem. Turbid water after launching appears due to a number of reasons, after studying which, the reservoir can be put in order.
What is the aquatic environment characteristic of new aquariums?
A few days after installation and start-up, the water in the aquarium dimmed dramatically. Why it happens?
- The fact is that in the "immature" reservoirs the biological environment has not yet formed, the beneficial bacteria have not spread enough, and are in a state of "stress." While they multiply massively, and after a few weeks, their colonies will adapt to the new reservoir. In old aquariums, bacteria do not multiply abundantly.
- The water in the new aquarium also becomes cloudy from the light particles of soil, which rises under the influence of frequent water changes. When pouring water directly on the ground, its pellets rise sharply, floating for a long time. This process creates a visual turbidity of water. To avoid this, it is necessary to make a careful and gradual injection of fluid into the tank. After this, the sediment will "calm down" and settle to the bottom. Purchased fish are unlikely to create a "hurricane" in a new home - they are shy and often hide in shelters. Water with sand sediment is harmless to fish and plants.
- Newbies in aquarism can overfeed the fish, because of what food remains to swim in the middle layers of the water, or settle to the bottom, mixing with the ground. Later, putrefactive bacteria that produce toxins multiply in the water. Ammonia, nitrates and nitrites - their decay products, which can poison all the inhabitants of the aquarium. It is better to give pets less food than to overfeed.
- Why do small particles of white precipitate appear in water? To purify water from turbidity, some owners of home aquariums immediately add water purification chemicals to the water. Before being introduced into the tank, they must be diluted in a separate container until completely dissolved. These substances, in addition to filtration, change the parameters of water. White sediments appear on snags, decorations and in the water itself, and the fish are not feeling well. In this case, pets are better moved to another capacity.
Watch the video about why the water in the aquarium grows cloudy.
- New water may cloud due to reproduction of single-celled algae. After the launch of the reservoir, where the lighting is too bright and the aeration and filtration system is poorly adjusted, the algae actively multiply, causing dregs.
- It is necessary to remember about ciliates - microscopic orderlies of water. In the early days, they also multiply rapidly, giving the water a milky white color. At this time it is impossible to colonize the fish, for a start let the parameters of the reservoir stabilize.
- The gray color of the water after start-up indicates insufficient washing of the gravel before laying. It is necessary to do the washing until it becomes crystal clear in running water. If the sediment does not disappear, it means that the stone contains impurities of phosphates, silicates and heavy metals. For accurate problem detection, it is better to use litmus paper with an indicator of an alkaline environment. Perhaps, it is worth getting rid of such gravel, replacing it with quality.
- After the launch, the water became dull brown, what to do? The reason is obvious - wooden decorations can paint water, and the use of peat to soften water or filter the soil imposes its brownish color on it. Tannin and humus are safe for fish, but they change the pH level, which may not be suitable for some types of pets. The following actions - get the snags from the water, and soak them for several days in infused running water. Fish evict, and replace the soil.
- If the water is dimmed and painted in an unnatural color (pink, black, blue) - look at the color of the soil and stones. Activated charcoal will help to bring water into ordinary color - it discolors the paint.
Recommendations for the operation of recently launched aquariums
After a new life in the aquarium wakes up, you need to do the necessary procedures so that no turbidity appears in it.
- In a new aquarium, do not partially refresh the water for 2-3 weeks until the microflora has stabilized. A complete change of water is harmful for both fish and plants.
- In order to avoid organic sediment at the bottom of the aquarium, you need to do fasting days for the fish. Give the fish as much food as they eat in 1-2 minutes. Unfinished food residues can be collected personally using a special siphon.
See how to properly feed aquarium fish.
- Install a quality filter and aerator in the aquarium. Часто мутная вода появляется из-за плохой системы очистки.
- Используйте тяжелый грунт с тонущей фракцией. Некоторые виды песка или гравия не способны осесть на дно даже через несколько дней после установки водоема. Такой грунт смертельно опасен для всех обитателей резервуара. Либо тщательно его промывайте, либо используйте более крупный песок.
Causes of green sediment in the tank
Why did the water go turbid and turned green - what to do about it? This question is often asked by novice aquarium holders. It has a simple answer - strong growth of algae (cyanobacteria). Turning on the abundant lighting above the reservoir, they thrive. Turbid environment with microscopic algae does not harm the fish, but it causes an ugly aesthetic appearance.
Daphnia and shade do an excellent job with water blooming. Transfer the tank to a shaded area where the algae will be sensitive and stop growing. Then start daphnia, but only so that the fish did not eat them. A large amount of daphnia can eliminate green water. Also, algae are eaten by common snails, which in a couple of days will clear the pond to shine.
Why on the walls of the new tank are visible small bubbles with air? The answer is: this is all due to untreated tap water, from which chlorine has not eroded. Such water smells sharply and has a slightly white tint. If the water for the aquarium correctly insist and do not fill it early, then this effect will not.
It is not recommended to settle the fish in insufficiently infused water - excess air is harmful for them. The circulatory system of waterfowl processes this air into bubbles, blocking the walls of blood vessels. As a result of this process, the fish get gas embolism and die. The first symptoms of the disease: edema of the whole body, rich dark color. Later, the fish begin to swim on their sides, do not let anyone near them. If you do not evict the fish in time, they will get worse. Restore the normal gas balance in this water, then the animals will survive and regain a healthy, beautiful look.
Why is the water in the aquarium muddy and stinks?
In general, there are a lot of reasons why water will deteriorate ... Improper lighting too much food is thrown into the water by the absence of filters in an aquarium, bacteria, etc.
For the night, the aquarium should be well treated first, then cleaned with boiled salted boiling water, the whole grund is boiled well in salt water, the algae should be examined if they are not bright green, not damaged, see if they are black dots if there is easier to throw out and buy New to heal, knowledge is needed, and you, I assume, are new to this, fish should be fed no more than once every 3 days and the food that you feed should be eaten in a minute and not set on the bottom of the aquarium and rot ...
after treatment, water must be poured at least 24 hours in the distance ... at least ...
Go to the pet store buy AKUTAN, this is a blue liquid, add it to the water at the rate of a cap of 10 liters ... and then run the fish for 3 days, the water will have a slightly white turbid but within 3 days it will change ... and the aquarium should stand in a dark place but have a good daylight lamp ... and do not forget about the number of fish at the rate of 1 fish 3-5 liters of water Ie per 10 liters of water no more than 2-3 fish of average size ... if possible, there should be a filter pump water should circulate and clean constantly good Other filters have cells for adding coal to ceramics. Well, they will tell you about this at the pet store, and so good luck, and if you ask anything ...
Apparently, either pour water not previously defended, or algae are bred there.
With algae can fight. There are water snails that devour them.
And be sure to plant a water in the water - a crochet - sold in the market. A plant that protects water from "dirt."
Perhaps the filter does not work well or something got started there that it is difficult to remove it just by changing the water. It can be algae (small ones at all) and then you need to buy in the pet store a means to combat such algae. Or just try again not just to change the water, but even boil the soil and boil over everything that you have installed in the aquarium
damn, well, what are you ?? ? Why change the water then ?? ? it is so necessary! You see, you probably planted the plants there, so from the plants of day 2, the water must grow cloudy, and then everything will pass !! ! and do not change the water so often !!!! it is generally very rarely changed, and the fish will die then ... everything is fine with your aquarium
maybe you have a lot of fish and the aquarium is small. 1 liter of water 1 fish about. Try boiling pebbles all, maybe there are bacteria that bred and multiply very good. quickly, water poured into the aquarium. but in general, the smaller the aquarium, the more worries with it !! ! It very often needs to be washed. but if it becomes cloudy in one day, then you need to look for the cause, and the fish do not die ???
* N *
In the aquarium, fish need oxygen, a water filter, and even the water does not like a lot of light (it starts to bloom).
If there are pebbles and shells, they should be boiled, water should be boiled and water should be poured and boiled again for 2 hours, the aquarium should be washed with soda, the plants should be washed thoroughly. Before you pour water into the aquarium, you need to defend the water for 3 days, then pour it into the aquarium, then put oxygen into the water and after 20 minutes you can let the fish.
The tank should be at least 25 liters. Otherwise, it will not be an aquarium, but crap! There necessarily need a filter and pump (bubbles). Sunlight should not be on the aquarium. Fish should be fed 2-3 times a day in small portions. Water changes no more than 30% at a time. Immediately start the fish can not be! It is necessary to first establish a biobalance. (about 4-5 days). Generally dig a good internet! You probably first have fish, then an aquarium, then plants, and then food. all the way around!
Why does the water in the aquarium with fish quickly grow cloudy? How often should it be changed?
I do not change the water, but replace 10–15% every week, combining it with a ground siphon and topping up with fresh water. It gets cloudy, you need to understand why. Do not get carried away with dry food, alternate with natural-frozen moth. And even better not to feed than to feed.
Usually, the water becomes cloudy due to the huge number of rotting bacteria that eat excess food. When feeding fish, it is important that they eat all the food in 10-15 minutes - everything that is not eaten should be removed from the aquarium. Once a week, siphon the soil with the help of a special siphon device (sold in the pet store and it is easy to do it yourself), at the same time about 1/5 of the water is drained and the fresh water is added.
It is not necessary to change the water entirely in the aquarium, it causes biological balance and leads to disease and death of fish and plants.
And, perhaps, you have an excess of fish with a lack of aquarium volume.
For the first time, flooded water always becomes cloudy at first, and then becomes transparent. Thus, the aquarium flora and fauna adapts its space. Disorder only when muddy water begins to stink. Water is poured only once. And then add as evaporation.
Well, the reasons for the many-problem start-up, overfeeding, overcrowding and estesSSno wrong care. For the exact answer, pliz in the section to fortunetellers. Without details it is impossible to answer. Defendants Mlyn, you will add water as you evaporate on the advice of Natalia Pusher-pick the fish, not immediately ... with time, as the concentration of ammonia increases.
Turbid water in an aquarium can be for various reasons, but it is not always easy to deal with the clouding of the aquarium. Turbidity in aquarium water may be due to suspended small particles of soil, which may appear after careless pouring water into your tank.
This is an innocuous clouding, and it does not cause significant harm to the aquarium inhabitants, after a certain time the turbidity will disappear by itself, due to its subsidence to the bottom. The aquarium will be cloudy from the appearance of a large putrefactive bacteria in it, and they are harmful both to the fish and to the plants in the aquarium. The appearance of such harmful bacteria in consequence, improper feeding of fish and excessive density of settlement of aquarium fish. For high-quality filtration of water in the aquarium, you should pour washed, coarse sand, a layer of 4 -5 cm, preferably a dark color. You do not need to completely change the water in the aquarium, periodically siphon the soil with a special siphon for cleaning the aquarium soil, removing all the dirt from the bottom of the aquarium, while adding 20% of fresh water, preferably the same temperature. In a properly equipped aquarium, biological balance is established and it stands for years without changing water. Muddy aquarium can be from improper feeding. Improper feeding leads to the most basic problems. From dry feed water in the aquarium very quickly deteriorates. Therefore, you should abandon the dry feed. If you still feed the fish with dry food, then you should feed them a little and make sure that all food is eaten immediately. The diet of fish should be varied, and in its composition should include live food. One of the best choices of live food is a bloodworm. It should be fed at the rate of 3 5 worms per day (small adult fish).
If none of the above mentioned things helped, try not to feed your fish for 2-3 days, this will not cause any harm to the fish, and the bacteria will die during this time. Remember the important rule: it is better to underfeed than to feed. Subject to these conditions, the water in the aquarium will be transparent. Chemical and biological processes in the aquarium occur constantly, as a result of all this, some plant organisms and animals are born, while others die. In the water column of the aquarium, there are many bacteria that are regularly processed by the remnants of food, decay products and plant activity and fish excrement. In turn, the beneficial bacteria are food for ciliates and other microorganisms. Water turbidity can occur in an aquarium where there are a lot of fish and few aquarium plants, and the water is not blown or filtered. An aquarium with such data is a good breeding ground for the mass reproduction of bacteria and unicellulars. In this case, you need to quickly precipitate extra fish into another aquarium. The reason for the turbidity of the water can also be fish, digging in the ground. This turbidity is harmless, and it is easy to eliminate by increasing the top layer of cleanly washed soil at the bottom of the aquarium. Such turbidity is harmless, and it is easy to eliminate, increasing the top layer of purely washed sand at the bottom of the aquarium. If you comply with all of these conditions, the water in your tank will be clear, clean and healthy. Water is replaced depending on the number of living plants and the density of fish planting according to the rules 1 time in 7–10 days (if the water is clean and the fish feel good then this procedure can be carried out 1 time per month and nothing bad will happen). There is a rule - the less you will climb into the aquarium, the longer the fish lives.
The water in the aquarium gets cloudy !!! Please tell me why?
This is completely normal. The aquarium is in the process of developing a biological system. Bacteria multiply which will recycle fish waste and food residues. Fish in the new aquarium is better to plant not all at once, but gradually. You immediately planted a lot, a lot of organic waste was formed, because the development of bacteria went very quickly, which is not very good.
Dry food should be given so much that the fish eat up all the maximum in 5 minutes.
The filter should work around the clock. Since you have live plants in aqua, the light should be on for 10-12 hours (turn off the light at night).
If it is possible, it is better to feed them with frozen food (frozen cyclops, etc.), throw a portion of food into a glass of water, after some time pour it into the aquarium.
Why does the water in the aquarium grow turbid?
Turbidity in the aquarium can occur for various reasons; to deal with these phenomena is not always easy. In the most harmless case, the water becomes cloudy due to small particles of soil suspended in it, for example, after careless 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 landing of fish in the aquarium. For good filtration of water, coarse-grained, cleanly washed river sand should be poured onto the bottom of the aquarium, preferably dark in color, 4–5 cm. Do not carry out a complete change of water in the aquarium, you only need to periodically remove the dirt from the bottom and fill up with fresh water of the same temperature. A properly equipped and well-contained aquarium can stand for years without changing water. It establishes the so-called biological equilibrium. The norm of planting fish 2 - 3 pieces in size 3 - 5 cm in 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 gradually and ensure that all food is eaten immediately. Great help here are snails, willingly eating the remnants of food. Properly formulated diet must necessarily include live food. One of the best feed is the bloodworm. It should be given on the basis of a rate of 3 5 worms per day for each adult fish of small size.
It is necessary to ensure that any food is eaten in 10 to 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. The perfect feed is the cortera 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, worms are easily divorced in a small box with earth. Daphnids and cyclops serve as good food, which you can catch yourself in some puddle using 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 utmost care: the water from the meat spoils very quickly. If the water has become cloudy, then we must stop feeding for a few days: the bacteria will die, and the fish will not be harmed. And there is one rule: it is better to underfeed than to feed. Subject to these conditions, the water in the aquarium will be transparent.
Many novice aquarists when cleaning an aquarium of a small capacity completely replace water in it, replanting fish and removing plants. This injures the fish and spoils the plants. 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 do not rush into stocking it. As a rule, on the second or third day, the water in the aquarium becomes turbid, as if a few drops of milk were dropped into it, because after a complete replacement of water, after some time, microorganisms usually grow rapidly and the water becomes cloudy. from the trash particles, and from the ciliates, the so-called "infusor cloud" arises.
The rapid reproduction of bacteria can manifest itself in your tank every time a large amount of water is replaced, and also in those cases where you forget to remove the remains from the tank in time.
we also had this problem. (aquarium is also 140 liters). it is you with new fish brought something. and they, as it were, with their microflora (from a store aquarium) brought into yours. It turned out a conflict. Personally, no means helped us. Out-change only water again.
And during the time of settling the water became cloudy, and then brightened. If not, you started the fish early. When starting the aquarium there is a struggle between the + and - bacteria. The "necessary" bacteria always win and the water brightens, which indicates the formation of bio-equilibrium.
Wait a couple of days - everything should come back to normal. Let's take the very least of the feed (micro ticker) and, of course, only the brand.
