All the reasons why greens appear on the walls of the aquarium

Aquarium fish - the choice of many people. They are quiet, do not litter, do not ask to walk at six in the morning and do not make races on sleeping owners at three in the morning. In addition, the aquarium is very lively interior, for its inhabitants is very interesting to watch, and care for all this good is relatively uncomplicated.

However, often "water house" begins to upset his owner. The water becomes cloudy, the walls begin to overgrow, an unpleasant smell can appear. There is a strong concern: whether these unpleasant manifestations will harm the residents of the glass house.

The first thing that comes to mind

The most common reason why greens appear on the walls of an aquarium is an excess of light. It may be too bright or too long. Direct rays of our Sun also have a negative effect on the state of water. The light favors the active reproduction of the simplest (single-celled) algae, which first “plant” the liquid medium and then begin to grow on the inner surfaces of the aquarium.

To deal with this is very simple. Shade a fish house. If the greens on the walls of the aquarium have not yet fully tightened them, the breeding process will at least stop. Snails and daphnids can destroy the attack. The latter must be run into the "pool" in such an amount that the fish do not have time to eat them. And if you want to diversify the population of the aquarium, buy catfish - they do an excellent job with thickets on the walls.

Some aquarists believe that partial landscaping gives good results during landscaping - naturally, with filtration. This is not true. On the contrary, such actions will lead to even greater growth of the green colony.

Hygiene and hygiene again!

The second most important factor explaining why greenery appears on the walls of an aquarium is its rare or careless cleaning. The uneaten food, the fallen leaves of underwater plants, the uncleaned sewage in time creates comfortable conditions for the active growth of the same single-celled algae. Most often, such accumulation creates excess feed. Observe pets: if they haven’t eaten a pile in a quarter of an hour, remove the rest, and further reduce the amount.

If you have a green aquarium wall, it can mean clogged filters or damage aeration equipment. It is necessary to check both that and the other at least once a month, and for filters - even more often.

And if the light is not enough?

In the first two cases described, a circumstance explaining why greens appear on the walls of the aquarium is excessive lighting: in the first one, in the second - indirectly, stimulating the rotting of the underwater garbage. And with such a problem is not difficult to cope.

However, the so-called diatoms, which like a lack of light, can cause plaque on the walls of the aquarium. For many "fish farmers" they appear in the winter if there is no additional lighting, and with increasing daylight they disappear by themselves. Such algae are unpleasant because they cling to the surface almost tightly. If you can tear them away from the glass, it is still possible, albeit with the risk of scratching, then there is no way from the plants.

Diatoms look like yellow or brown flat formations. The first step will naturally be an increase in light. However, if this did not help, then the reason is the presence in the aquarium water of a significant concentration of silicates. Accordingly, you will have to go to the pet store for the filter, absorbing them.

Multicellular evil

So far, they have been talking about unicellular unwanted "neighbors". However, the most terrible enemy are multicellular - cyanophytes. They are the reason why greens appear on the walls of the aquarium, with a bluish or brownish tinge. They begin to spread from the bottom, then they crawl along the walls and plants with unpleasant thick mucus. They can also form floating islands, making it difficult for oxygen to enter the aquarium.

The nitrogen-containing compounds are to blame for cyanophytes, and again, an excess of light contributes to rapid reproduction. It is very difficult to remove these algae, it is better to prevent their generation. First of all, it is necessary to plant many plants at once in a new aquarium, combining them with floating species that grow quickly (fit the elodea, nyas or pemphigus), it is better to lower the pH of the water to the mark 6. Algae-eating fish will also be very helpful in the difficult struggle. The smallest colonies of blue-green pests must be immediately cleaned. If you are lucky and if the process is not too running, you will win them. If not, you will have to re-equip the aquarium.

The good news is that blue-green algae in a healthy glass house does not survive, so this attack happens quite rarely.

Why is the green water in the aquarium

One of the most frequent questions asked by all aquarium lovers is why does the water in the aquarium turn green even when it is regularly replaced? Despite the fact that the green water does not bring tangible harm to the inhabitants, the aesthetic appearance of the aquarium nevertheless deteriorates. Such water will be dangerous for those fish that run into it from a clean, fresh pond. To choose the most effective method of dealing with euglene, which causes the flowering of aquarium water, it is necessary to establish the exact causes of this phenomenon.

Causes of the phenomenon

An unpleasant bloom of water in an aquarium can be caused by several reasons that both beginners and experienced aquarists should be aware of. So why the water in the aquarium turned green? What was the cause?

  1. Incorrect lighting.
    Most often, the blooming of water in an aquarium occurs because of ignorance of the elementary rules of its illumination. The reasons may be:
    • excessive lighting of the aquarium: an excess of sunlight falling on it, provokes enhanced growth euglena;
    • wrong light mode for the season.
  2. Water pollution Often the water in the aquarium turns green if there is a pollution of the aquarium water with various organic substances. It can cause:
    • reproduction of euglena - plants of lower level, floating unicellular algae of small size;
    • accumulations of soluble organic waste in water;
  3. Improper feeding Beginners of the aquarium may not know the rules of feeding the fish, which will lead to water flowering:
    if you pour too much food into the tank, which the fish will not eat right away, it will sink to the bottom of the tank and rot, and thus the green water in the tank will be provided to you.
    All these causes can be easily eliminated in many different ways.

Methods to eliminate

If the reason for greening the water in the aquarium is determined correctly, you need to choose the best way for you to eliminate this cause.

  1. If it's about lighting ... It was necessary to think about the lighting while installing the aquarium, but if it is too late to change something, you can take the following measures to clean the water from blooming:
    • the aquarium should be darkened: if the algae are deprived of direct sunlight, they will die, making the water brighten;
    • ensure that the aquarium has the correct light mode: in the winter it should be lit no more than 10 hours a day, and in the summer - up to 12 hours.
  2. If water pollution occurs ...
    To quickly and effectively clean the water from the invasion of green evil, you can use the following tips:
    • run a large number of live daphnids into the aquarium — enough so that the fish cannot eat them at a time: the daphnias will shortly deal with the algae that have filled the aquarium’s space and purify the water;

    • buy special preparations from green water in aquariums, which can be found in any pet store;
    • start in your aquarium creatures that feed on algae and help you in the process of lightening the water: mollies, catfish, pecilli, snails or shrimps;
    • if the water in the aquarium is blooming, in no case do not try to change the water again and again - this will provoke even more rapid growth of algae;
    • if the soil is contaminated with organic waste, transplant the inhabitants of the aquarium into a separate container and clean the soil;
    • check the correct operation of the aquarium equipment;
    • try a chemical cleaning method: streptomycin powder is diluted in water and added to the aquarium (3 mg of solution per liter of aquarium water); for fish, such aeration is harmless, but with algae that have filled up the aquarium will cope in a short time;
    • There are special filters for eliminating green water: for example, a UV sterilizer that kills algae with the help of directional ultraviolet light;
    • diatomaceous filter;
    • use flocculants (or coagulants) - these are special additives from small particles that effectively remove algae from the water;
    • Aquarium water filtration can also be done using micron cartridges.
  3. If the reason for feeding the fish ... If you find out that the water in the aquarium has turned green due to improper feeding, study the instructions on how to properly feed the fish and follow them exactly so that the fish will be good and you will enjoy the cleanliness of your aquarium.

Prevention

In order to permanently save yourself from the problem of aquarium water flowering, it is easiest to prevent this unpleasant phenomenon. Observe preventive measures, monitor the proper operation of the aquarium equipment, properly care for the aquarium as a whole. These measures include:

  • correct installation of the aquarium from the very beginning: do not put it directly to the window - the source of direct sunlight: it must be at least one and a half meters away from such a source; better provide artificial light to the aquarium using lamps;
  • when installing, take care that the soil was poured into the aquarium at an angle to the front wall, which will facilitate the process of cleaning and cleaning the soil from various impurities;
  • proper feeding of fish: do not give a lot of feed; make sure that they eat it all in 5 minutes;
  • proper care: keep the aquarium clean at all times, remove rotten algae leaves in a timely manner.
    Finding out why the water in the aquarium is blooming, try to solve this problem as soon as possible, in order to bring comfort to your fish and enjoy the aesthetic view of clear, crystal clear water.

Why is the water in the aquarium green?

The most common question that interests all aquarists is why is the water and soil in the aquarium turning green? Despite the fact that the blooming water does not cause much harm, but the aesthetic appearance deteriorates quite noticeably. Such water can become dangerous for fish if run from a fresh pond. To choose a method to combat this problem, you need to establish reliable causes of flowering.

Why is the aquarium green?

The cause of the turbidity of the water is considered "euglena", known as free-floating alga. It is an integral part of the food chain and quickly adapts to environmental conditions.

The national name "green water" accurately describes the appearance of the vessel, in which such alga is present. Most often, aquarium owners are faced with a problem eugle some weeks after launch. But why does the water turn green in the aquarium and the algae reproduction begins? There are several reasons:

  1. Wrong lighting. Excessive light triggers the growth of small algae. If the lighting in the aquarium works for more than 10 hours, then this can be considered favorable conditions for the development of euglena. Starting the aquarium lighting should be turned on for 4 hours, adding a couple of hours in 3 days.
  2. Excess ammonia. That it is often available in new aquariums and with large-scale changes of fluid. Watch out for the composition of the water you are adding and this problem can be avoided.
  3. Improper feeding. Overfeeding the fish can cause water bloom. Excess food, not eaten by fish, will settle at the bottom and will be the main reason why the stones are green in the aquarium.

What to do if the walls of the aquarium turn green?

First you need to eliminate the causes evgleny. If the matter is in the wrong light, either set a suitable light mode, or deprive the aquarium of direct sunlight. If the reason is unknown, then you can resort to the methods:

  1. Run into the water a lot of living daphnia. They will quickly deal with small algae and clean the water.
  2. Get drugs from Euglena.
  3. To lead creatures that lighten the waters: catfish, mollies, snails, petilia,
  4. If the soil is contaminated with organic waste, transfer the fish to another tank and clean the soil.
  5. Use diatomaceous filters, UV sterilizers or micron cartridges.

By following these tips, you will keep the water in the aquarium crystal clear and fresh.

What caused the bloom of water in aquariums?

Almost all aquarium lovers ask the same question: why is the water in the aquarium turning green? And although this phenomenon does not harm the inhabitants of the small underwater world, from the point of view of aesthetics, the aquarium view is spoiled. In addition, the green water in the aquarium will be disastrous dangerous for fish running directly from a clean pond.

We will try to figure out why water is blooming, and what to do about it.

Main reasons

Water blooms for various reasons, and therefore you need to have a general idea of ​​all of them. So:

  • First of all, improper lighting can spoil the water in the aquarium. This is due to the fact that the aquarist simply does not know the simplest rules of lighting. Water may bloom due to excessive lighting in the aquarium or due to improperly selected light mode for the season;
  • also, the water in the aquarium may bloom due to pollution;
  • finally, another reason for the bloom of water is improper feeding.

Often, beginning aquarists, because of ignorance of the key feeding rules, themselves provoke the fact that the water is green. This may be caused by a large amount of feed. Since the fish do not eat much at once, the remains of food settle to the bottom of the aquarium and begin to rot.

That is why there is a blooming of water in the aquarium. Accordingly, in order to prevent this, it is necessary not to make the listed errors. But what if the water in the aquarium has already become green?

Elimination of provoking factors

It is clear that you will need to clean the aquarium and change the water. True, you should not just constantly change the water. The fact is that the algae will only multiply more actively. But you also need to eliminate the cause. Above, we examined the main factors that cause water blooming. If these factors are established correctly, the following measures can be taken.

If the cause is lighting

Objectively speaking, the issue of lighting is solved even during the installation of the aquarium. But if this has not been done before, you can do the following. First, try to darken the aquarium slightly. Secondly, try to ensure the appropriate light mode for the season. This means that in the winter the underwater world should receive coverage about 10 hours a day, while in the summer it will take 12 hours;

If it's pollution

In this case, you need to quickly and efficiently clean the water. In this issue you can take into account several useful recommendations.

  • So, you can run more daphnids alive. A little more means as much as your fish cannot eat at a time. The fact is that daphnias effectively deal with algae that fill the space under water;
  • You can also purchase special drugs that are designed specifically for cases with green water. Such drugs are sold in almost all pet stores;
  • An effective way would be to settle into the aquarium of such creatures who love to eat algae and, therefore, help in matters of water clarification. Such creatures include mollies, snails, shrimps, catfish;
  • If soil contamination is observed, it should be thoroughly cleaned. At this time, the inhabitants of the aquarium should be transplanted into a different container;
  • It is possible that the pollution is due to equipment malfunction, so it is worth checking its condition;
  • They also recommend using a chemical cleaning method. Its essence lies in the fact that streptomycin powder dissolves in water, and the resulting solution is added to the aquarium. Do not be afraid, because this method is absolutely safe for fish;
  • In addition, there are specially designed filters to eliminate green water. For example, there is a sterilizer that destroys algae with ultraviolet rays.

If contamination is caused by improper feeding

Everything is very simple here. If you have accurately determined that water is polluted due to improper feeding, then you need to carefully study the relevant instructions. To properly feed the fish, you will need to strictly follow the instructions of such instructions.

Thus, to eliminate the flowering of water in the aquarium is quite simple. But for this it is important to determine why this is happening.

The raid in the aquarium, on the walls and stones: green, brown, brown, white, mucus in the aquarium!

All types of aquarium plaque.


Green scurf in aquarium,
white bloom in the aquarium
mucus in the aquarium !!!

Данная статья посвящена такой проблеме "аквариумной гигиены", как налет на стенках аквариума. Итак:

First of all, налет на аквариумных стенках или стеклах образуется не от хорошей жизни аквариумного мира - проще говоря, в Вашем аквариуме, что-то не так. И для ликвидации любого налета на стенках аквариума, в первую очередь необходимо восстановить balance of aquarium environment. This is achieved by proper and regular cleaning of the aquarium, as well as the use of necessary drugs in case of deviation from the norm. It should be noted that excessive care: cleaning and changing aquarium water can also lead to adverse consequences. Accurate recommendations regarding this issue are difficult to give, because it all depends on: the volume of your aquarium, the types of fish, plants, the location of the aquarium, etc. In general, you should follow general guidelines - i.e. recommendations on weekly cleaning of the aquarium and cleaning equipment. I would also recommend you to remember that "old" aquarium water is always better than fresh water - do not overdo it with cleaning and changing water. Remember the balance of plants and fish, never overload the aquarium, do not make him a hostel. In your arsenal should always be the primary means of response: aquarium coal, methylene blue or malachite green.

Secondly, all types of raids - "clouding of the aquarium wall", caused by various factors or pests. Actually, therefore, all the attacks can be divided into color: on green raids in an aquarium (green-brown), white raids in an aquarium (whitish) or aquarium mucus.

How to deal with them? ... Simple enough!

Relative to green scale on the walls of the aquarium, which can also be formed and the decorations of the aquarium (artificial plants, stone). This plaque is caused by excessive "water bloom" - the formation of an uncontrolled amount of algae. This plaque is caused by the lack of care for the aquarium and as a result of an excess of organic matter (ammonia decomposition products).

Remedy: clean the aquarium, replace the aquarium water with fresh water, turn off (do not turn on the backlight), increase the filtration and aeration of the aquarium; in the pet store you can buy tablets from “blooms” - from algae. I will cite as an example, one of them - TETRA tablets for algae control.

TetraAqua AlgoStop depo - It is soluble pills to control the development of algae. Effectively destroys various algae in freshwater aquariums, including "black beard" and blue-green algae, and also prevents their further growth.

Mode of application: Tablets are placed on the ground in the free flow area. The drug lasts for 6 weeks, after which the tablets are removed from the water. Tablets contain a complex of substances that are gradually released into the water. The tablet does not dissolve completely, but retains its original shape. After 6 weeks, it ceases to release the active substances and must be removed from the water. The slow dissolution of the drug in water allows you to use the active substances AlgoStop depot, for a long period of time. With proper use of the drug does not harm aquarium fish and plants.

Dosage:For prevention: 1 tab. on 50 l. water. For the destruction of filamentous algae: 1 tablet per 25 liters of water.

The article on other Tetra algae tablets is here!

The above preparations also cope with other types of algae with brown patina (diatoms), filament (green threads), black villi (black beard).

Aquarium: walls, decorations or equipment covered with white bloom - whitish mucus, what to do?

The appearance of whitish mucus is a frequent problem in new aquariums. It occurs because of the excessive content of organic substances in water (PJ, dead organic matter). White scurf consists of numerous colonies of saprophytic bacteria, which actually feed on excess organic matter. These bacteria and mucus are harmless, they do not harm hydrobionts. But their presence is unpleasant to the eye and speaks of the delicate biological balance in the aquarium. As a rule, mucus envelops natural snags (the place of the highest concentration of organic matter). Often, abundant colonies are observed on the walls of the aquarium in the place where the flow from the filter is directed - the bacteria "catch the sweets with the wind", which gives them a stream of water.

This slime is removed simply - mechanically. Some aquarists are advised to have antsistrusov or others fishermenthat will clean up the mucus. But even without this, the raid will disappear as soon as the biological balance is tuned. To make this happen faster, it is recommended to enhance filtration, reduce the amount of feed, that is, in every possible way contribute to the reduction and rapid oxidation of PJ. From aquarium preparations can be proposed to apply Tetra Bactizim and Tetra SafeStartwhich will promote the growth of colonies of beneficial nitrifying bacteria and, therefore, reduce the concentration of poisons.

The water in the aquarium turns green during the day !! ! We change every day, and to no avail: (((What happened ??? How to cure water ???

Annie

In the summer, with strong aquarium lighting and high water temperatures, it can turn green. This is the result of the mass reproduction of microscopic algae, most often euglene green.
Sometimes microscopic algae also appear in large quantities in an aquarium, which cause whitish-green turbidity of water. And these algae develop under strong illumination of the aquarium.
When the bloom of water has not gone too far, it does not cause much harm to the fish, unless, of course, these fish did not suddenly fall into such water.
To get rid of the greening of water, the aquarium should be completely closed with a cloth that does not transmit light, or shade it in any other way. Keep the aquarium in this form should be to the clarification of water.
The second old, tried-and-true method of dealing with water blooming is as follows. A lot of daphnids are allowed into the aquarium: as many as the fish cannot eat quickly. And these crustaceans destroy algae: they feed on them. Only one day daphnia make the water crystal clear.
It goes without saying that a lot of daphnids can be released only in an overpopulated aquarium, since with a lack of oxygen the crustaceans will die, increasing the spoilage of water.
Water will not bloom in an aquarium if the wall of it, on which the sun's rays fall, is covered with rare gauze or a piece of thin white paper.
Often the greening of the water is not only due to the excessively strong illumination of the aquarium, but also due to the fact that too much organic residue accumulates at its bottom. If so, you must first remove them.
Green algae deposits on one or two walls of an aquarium, on devices that were in the water, on plants are usually harmless. As a rule, simply clean the glass of the aquarium with a scraper. And in order to avoid an excess of algae on plants and devices, fish are allowed into the aquarium, for example, some species of tooth-eating fish that eat them. A temporary shading of the aquarium or, if the artificial light is too bright, helps reduce the lamp power.
When green algae, rather than green algae, appear on glasses, appliances and plants, this indicates that the aquarium is lit very poorly. Brown algae usually appear in winter in aquariums devoid of artificial light.
In such aquariums and plants fall ill. Their leaves and stems turn pale, turn yellow, become thin, flabby, begin to rot.
To cure plants and get rid of kelp you can, putting the aquarium in the lit place, but it is better to install a lamp above it.
To the worst enemies of aquariums include blue-green algae. They multiply unusually quickly and inhibit the growth and the very life of plants, covering their leaves with a smelly film.
It is necessary to fight these algae as follows: clean the aquarium glass and devices with a scraper, carefully remove the film from the leaves of the plants with your fingers, and remove the dirt from the bottom of the aquarium with a hose with a hose. In addition, it is necessary to loosen the soil and put into the aquarium fish that feed on algae, they need to be fed moderately.
In addition to blue-green and other algae, filamentous algae often breed on the illuminated walls of aquariums and on the leaves of plants. If they are bred a lot, they may be confused and die small fish.
With filamentous algae, the following methods of control are possible: reduce the amount of light falling on the aquarium, settle as many snails of coils in it, put fish into it, eagerly eating yarn.
In a warm-water aquarium, these algae eagerly eat mollies with greed, and other viviparous fishes eat them, though not with such appetite.
In the cold-water aquarium, the redgrass is superbly destroyed by ruddies and bitters.
Many species of fish can be accustomed to eating yarn, however, provided that there are several mollies in the aquarium. Imitating them, the fish begin to eat algae.

It is because you change the water every day and no sense. If this is a new aquarium, then greening is a normal process, a microcosm is formed in the aquarium, certain types of bacteria are diluted. We also had, it was difficult to breathe near the aquarium, the water was already muddy (this state was about a week, then brightened again, and so alternated a month and a half or two. Now the water is clear, there is no smell). Just once every 2 weeks it is necessary to add a little of the settled water, to look so that there is no direct sunlight, you can, of course, special. buy liquid, but we did without it. And do not pour food.

You need (just inevitably) to clean the entire tank and the contents inside it. If you find real pure silver you can put it from the bottom, there will be no harm. Pour clean river water, it is still necessary to find clean river water! Good luck to you! The aquarium is very beautiful - it requires a lot of hustle and bustle. But beauty !!!

Do you put special bacteria in an aquarium? To create the right microflora and microclimate they are non-volatile. You need to put a bag of bacteria on the bottom of the aquarium and run the fish only a week later. Also in the pet store sold special fluids to suppress the growth of algae. When changing water, by all means take water from the bottom, use a special siphon for this ... Do not drain the upper and middle layers ...
Aquarium is great. You will succeed! Good luck to you!

the first is to thoroughly wash the pebbles and the aquarium itself. the second is that the water should be left for at least two days. How tall are you? put an aerator (air supply compressor. it has a filter) and remove the aquarium from the light. do not feed the fish too often; it is filling up the aquarium.

If your fish blacken their noses (read in the comments), then in this case it comes from too frequent changes of water, and, perhaps, settled less than 3 days. Partial or total darkening occurs with chlorinated water. Sometimes the edges of the fins and tail whiten. That your fish have no diplomatosis and no other diseases, that's for sure. In this case, it is on the quality of the water. If you continue in the same vein, the fish will die. About silver (harm) I wrote in the comments to the answers about silver.
Many aquarists when cleaning an aquarium with 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 not rush into its “stocking”. 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 are usually rapidly developing, brought to the aquarium with fish and plants, 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 aquarium every time you replace a large amount of water, and also in those cases when you forget to remove the remnants of uneaten food (especially dry), rotting plants from the aquarium in time. Such clouding, if you eliminate its cause and wait a while, passes.
In the aquarium constantly occur interrelated biological and chemical processes, as a result of which some animal and plant organisms are born, others die.
A huge mass of bacteria that lives in the water column and in the ground processes the decay products and the vital activity of plants, food remains, fish excrement. Bacteria in turn are food for ciliates, etc.
If you do not change the water to a new one, as many inexperienced aquarists do, fearing cloudiness, then after a week or two the bacterial turbidity disappears and the water becomes crystal clear.
In an overpopulated aquarium, turbidity in the water can occur, especially if there are few plants in it and the water is not blown or filtered. In such an aquarium, accumulated metabolic products serve as a good nutrient medium for the mass reproduction of bacteria and unicellular organisms. In this case, you need to quickly precipitate extra fish. If the situation is not corrected in time, it can lead to illness and even mass death of fish, not to mention that such an aquarium looks ugly.
The water in the aquarium can turn blue from 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 soil with a layer of 4-5 cm should be poured into the bottom of the aquarium. A full change of water in the aquarium should not be carried out, it is necessary only with a hose with a tube periodically (1 time in 3-4 weeks depending on the volume of the aquarium) remove dirt from the bottom and add fresh water of the same temperature in the amount of 1/3. A properly equipped and well-contained aquarium can stand for years without a general cleaning with a complete change of water. It establishes the so-called biological equilibrium. The rest of the time, add to the evaporated one and replace no more than 1/10 or 1/15 of the volume. The maximum rate of landing fish 2 - 3 pieces in size 3 - 5 cm in 1 - 3 liters of water.

Maybe to start reading literature about aquariums ?? ? Why do you change EVERY day water? And changing every day where you take it from - from the tap ?? ? She does not have time to defend - 3-4 days it takes!

Do not change so often the water will not change anything, only worse for the fish will be, put the filter, I put the filter and bought special droplets for microflora. //www.aqua-shop.ru/index.php/cPath/61_206 look here.

Why is the water green in the aquarium?

Thoroughly clean the bottom of humus, change half of the water and throw a good bunch of roquilla or a small pemphigus on the surface. Due to the rapid growth (the rodentweed can grow up to one and a half meters per week) excess nitrogen will be removed from the water, due to which an explosion occurs in the reproduction of unicellular algae, the so-called. water bloom. Plants goes without saying
must be taken from aquariums and not in any way in natural waters. In the future, do not forget to thoroughly clean the bottom and replace the water. And another thing: the light in the aquarium should be only artificial, at the rate of 0, 5 watts of fluorescent lamps per 1 liter of water, the length of the day should be at least 12 hours. Avoid sunlight.

Wash the tank thoroughly before use, without using any detergent. Sand repeatedly washed and calcined in the oven. Cover it with the bottom of the aquarium obliquely (at the front wall with a height of 3 cm, at the back - up to 6 cm). You can place multi-colored sea pebbles on top of the sand, also pre-boiling them in water. Put a sheet of clean thick paper on top so as not to erode the sand when pouring water and fill the aquarium to a height convenient for planting. Defend the water during the day and filter. If possible, take a portion of the water in a clean natural pond and filter too. Such water will help establish a biological balance in the aquarium. Carefully plant in the sand the simplest aquarium plants - vallyseria, hornolistnik, water fern.
The walls of the aquarium quickly covered with simple algae, but it is desirable to clean only the front sight glass: algae are the most valuable suppliers of oxygen.
Sometimes, as a rule in summer, with good lighting and high temperature, the water in the aquarium turns green. The old, proven way to combat blooming and bacterial cloud is to launch daphnids or tadpoles into an aquarium. During the day the water in the aquarium will be crystal clear. After doing the work, do not forget to release the tadpoles. Specially selected homeopathic preparations help to establish biological balance in an aquarium.
Plants are not only a source of oxygen and pleasing to the eye. They are an excellent vitamin supplement for some species of fish. Fish, in turn, provide plants with nitrogenous compounds.

скореее всего, у Вас аквариум стоит под воздействием солнечных лучей. или используете для освещения обычные лампы накаливания либо в аквариуме очень теплая температура воды, что тоже может привести к зацветанию аквариума. Try to change the water more often (on average it is necessary to change 1/3 the amount of water once a week).

When the bloom of water has not gone too far, it does not cause much harm to the fish, unless, of course, these fish did not suddenly fall into such water.
To get rid of the greening of water, the aquarium should be completely closed with a cloth that does not transmit light, or shade it in any other way. Keep the aquarium in this form should be to the clarification of water.
The second old, tried-and-true method of dealing with water blooming is as follows. A lot of daphnids are allowed into the aquarium: as many as the fish cannot eat quickly. And these crustaceans destroy algae: they feed on them. Only one day daphnia make the water crystal clear.
It goes without saying that a lot of daphnids can be released only in an overpopulated aquarium, since with a lack of oxygen the crustaceans will die, increasing the spoilage of water.
Water will not bloom in an aquarium if the wall of it, on which the sun's rays fall, is covered with rare gauze or a piece of thin white paper.
Often the greening of the water is not only due to the excessively strong illumination of the aquarium, but also due to the fact that too much organic residue accumulates at its bottom. If so, you must first remove them.
Green algae deposits on one or two walls of an aquarium, on devices that were in the water, on plants are usually harmless. As a rule, simply clean the glass of the aquarium with a scraper. And in order to avoid an excess of algae on plants and devices, fish are allowed into the aquarium, for example, some species of tooth-eating fish that eat them. A temporary shading of the aquarium or, if the artificial light is too bright, helps reduce the lamp power.
When green algae, rather than green algae, appear on glasses, appliances and plants, this indicates that the aquarium is lit very poorly. Brown algae usually appear in winter in aquariums devoid of artificial light.
In such aquariums and plants fall ill. Their leaves and stems turn pale, turn yellow, become thin, flabby, begin to rot.
To cure plants and get rid of kelp you can, putting the aquarium in the lit place, but it is better to install a lamp above it.
To the worst enemies of aquariums include blue-green algae. They multiply unusually quickly and inhibit the growth and the very life of plants, covering their leaves with a smelly film.
It is necessary to fight these algae as follows: clean the aquarium glass and devices with a scraper, carefully remove the film from the leaves of the plants with your fingers, and remove the dirt from the bottom of the aquarium with a hose with a hose. In addition, it is necessary to loosen the soil and put into the aquarium fish that feed on algae, they need to be fed moderately.
In addition to blue-green and other algae, filamentous algae often breed on the illuminated walls of aquariums and on the leaves of plants. If they are bred a lot, they may be confused and die small fish.
With filamentous algae, the following methods of control are possible: reduce the amount of light falling on the aquarium, settle as many snails of coils in it, put fish into it, eagerly eating yarn.
In a warm-water aquarium, these algae eagerly eat mollies with greed, and other viviparous fishes eat them, though not with such appetite.
In the cold-water aquarium, the redgrass is superbly destroyed by ruddies and bitters.
Many species of fish can be accustomed to eating yarn, however, provided that there are several mollies in the aquarium. Imitating them, the fish begin to eat algae ...
