Green water in the aquarium how to fight


Why is the water green in the aquarium and how to deal with it?

Self-purification of water in natural aquatic ecosystems occurs due to physicochemical and biological processes involving hydrobionts: living organisms and plants. The condition of the aquarium water depends on the organization of the system (maintenance mode, power and type of filter, the presence of living plants, drifts, the number of fish and food). The color of water can change under the influence of various factors. Thus, the low content of oxygen in it, which is consumed for the oxidation of organic matter, leads to an increase in the concentration of decomposition products. The water becomes cloudy, gets the smell of hydrogen sulfide. But there are cases when it becomes green. So why is the water green in the aquarium?

The reason for its turbidity is the mass reproduction of bacteria, and the water turns green usually from green microscopic euglenic algae that multiply in an aquarium. Euglena is normally always present in the aquarium, but during its reproduction begins the "flowering" of water, which can be painted in yellow-green, green colors. More often it is observed in aquariums with excessive brightness of the light source. Often, fans of ornamental fish, acquiring aquariums for the home, place them in the most convenient and "cost-effective" place - near the windows. Direct intense sunlight contributes to the active reproduction in water of green algae, which cover the glass aquarium, decorations, plants. Strong artificial lighting also contributes to the reproduction of euglena. It can be brought into the aquarium and with live food for fish from natural waters.

The first actions that are taken by novice aquarists are a complete replacement of water, cleaning plants, decorations. Similar, logical at first glance, events only aggravate the situation, causing bewilderment and the question of why the water is green in the aquarium, despite all efforts.

Changing water does not improve the situation. It is necessary to eliminate the causes of its "flowering" - turn off the light for several days, obscure the aquarium, located near the window. After this, the regular change of water and cleaning of the soil will allow to correct the situation, since light and nutrients only stimulate the growth of green algae. Keep the aquarium clean at all times.

You should know that the process of water self-purification will accelerate with the addition of "old" water (1/3 of the total) to the aquarium, pre-stored, rich in humic acid and a set of microorganisms that help restore a healthy environment. You should know that it is harvested from a prosperous aquarium, not overcrowded with fish, with well-growing plants.

In order not to wonder about why the water is green in the aquarium, you can run daphnias into it. In this case, it is better to seed the fish so that they do not destroy the crustaceans.

You can also purify water with the help of special preparations acquired in pet stores. Algae die off when a solution of rivanol, trypaflavin, penicillin, streptomycin is added to the aquarium.

Special diatomaceous filters and UV sterilizers help to eliminate the "blooming" of water.

In order to no longer wonder why water is turning green in an aquarium, it is necessary to achieve the necessary biological balance for its aquarium inhabitants. To support it, you need to adjust the lighting: apply curtains, screens, change the power of the lamps. Remember that it is important where the aquariums are installed. The fish will feel great with proper lighting, proper feeding, aeration and filtering.

It is useful to acquire new inhabitants of the underwater world who eat algae. These are pteregoplichts, antsitrusy, which remove plaque from glasses, mollies, Siamese seaweeds, Japanese shrimps, snails, ampouleries.

Why is the water green in the aquarium?

"Flowering" of water is typical for various reservoirs, including home aquariums. Water usually turns green in the summer - in July or August, this process can be accompanied by an unpleasant smell and death of the fish. To get rid of the "flowering", you need to find out its cause.

The question "opened a pet shop. Business is not going. What to do?" - 2 answers


1. In addition to fish, snails, plants and other living creatures, plankton lives in an aquarium, causing water to bloom - filamentous and unicellular green algae. In conditions of medium or low light, low water temperature, phytoplankton multiplies slowly, the water remains clear. Some factors contribute to the intensive increase in the mass of microorganisms.

2. The most basic reason for the enhanced growth of microscopic algae is a large amount of light. If the aquarium's lighting is too intense, the water may turn green even in winter. In the summer, there is enough natural daylight to “bloom”, especially if the aquarium is in direct sunlight.

3. The second important factor in the "blooming" of water is the increase in its temperature. The active division of phytoplankton begins when the water temperature becomes higher than the average annual.

4. The presence of excessive amounts of organic matter in water is another factor contributing to the growth of microorganisms. If you poorly conduct aquarium hygiene and regularly overfeed the fish, phytoplankton, especially Euglena green, begins to divide in this nutrient medium.

5. The last factor affecting the purity of the aquarium is the lack of clean water. If you save on the filter and aeration, chemical and chemical balance of water suffers, which leads to the transformation of the aquarium into a "swamp".

6. The most radical way to get rid of "flowering" - a complete replacement of water, followed by shading the aquarium. If it is problematic to completely change the water, it can be changed to a third and cover the aquarium from the light. Without illumination, phytoplankton will cease to multiply, and infusoria, for which it is food, will purify water. In addition, the aquarium can be populated with daphnia, shrimp, catfish, snails, which also feed on microscopic algae.

7. If the water is green - reduce the amount of food for the inhabitants of the aquarium. Normally, fish should eat everything in 5-15 minutes. For a day or two, you can even completely stop feeding - the fish will have enough of the food that is already in the water. Watch also for the proper operation of the devices for filtering and aerating the aquarium - this helps to avoid excessive accumulation of organic matter in the water.


A slight greening of the water for the fish is not considered dangerous, but if the “bloom” is strong enough - it can be fatal for some inhabitants of the aquarium. Green algae litter the gills of fish, and in addition, at night, phytoplankton needs oxygen, as a result of which the “official” inhabitants of the aquarium begin to choke.

Helpful advice

If all your efforts do not lead to water purification, try using chemicals - they can be purchased at pet stores. At observance of the instruction and the specified doses these substances are safe for inhabitants of an aquarium and plants.

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.

How to get rid of green algae in the aquarium

Many aquarists at least once, but faced the problem of fouling the aquarium with green algae. They easily adapt to different conditions and grow quickly. The sooner you start fighting them, the sooner you get rid of them.

The question "HOW baby to retrain to go to the tray (she is 4 months)?" - 3 answers

You will need

  • - snails;
  • -somics;
  • -chemicals.


1. The most effective means of combating green algae is to reduce daylight hours to 6-8 hours. Also should reduce the brightness of the illuminating lamps.

2. Seaweed they do not like being touched or moved. It is therefore necessary as education to collect them siphon or wound on a stick. Increase the filter capacity so that a strong stream of water prevents the algae from settling. On the contrary, aeration should be reduced. Seaweed do not like a small amount of oxygen in the water. Also launch the plants floating on the surface of the aquarium - they will shade the algae.

3. Once you notice the green algae, change the water change mode to aquarium. Try to change 10-20% of water daily. So you will not let algae get used to the aquarium environment.

4. Pet shops sell special products for the prevention and control of green algae. But carefully read the label - they are harmful to some types of aquarium plants. Chemicals do not eliminate the cause of algae. They eliminate only the visible greens, but disputes still remain. If you need an emergency method of dealing with green algae, then these drugs are just for you. After these funds, conduct the above methods for a week for prevention.


If you can’t get rid of green algae, then as a cardinal method you can re-launch the aquarium. To do this, prepare a new distilled water. Wash the aquarium and all accessories with chlorine.

Helpful advice

Some species of fish (catfish, mollies) eat green algae. They will save you from the greenery in those places where you find it difficult to reach. Snails that feed on algae and food debris can be an alternative to fish.
Before planting new plants in the aquarium, be sure to wash them in a special solution. It is prepared using a 5% bleach solution, which must be diluted with water at a ratio of 1:20.

The trouble of the aquarium - the appearance of filamentous algae

Filamentous algae is a true aquarist nightmare. Barely appeared in the aquarium, these thin green strands, like hair, braiding plants and stones, begin to grow rapidly. In a matter of days, they can flood the entire room reservoir, and it is very difficult to get rid of them.

Growing, the algae emit an excess amount of waste into the water, entangle plants, interfering with their growth. The algae stuck to the remnants of food, fish fry may get confused. All this leads to active processes of decay in the aquarium, and if the process is started and nothing is done with it, even lead to the death of the bio-system.

Algae and plants are natural competitors

First of all, you need to understand that algae and aquatic plants are completely different things. Plants are higher, complexly organized beings, they have different departments in their structure: root system, stem, leaves, shoots. Each organ consists of its own type of cells. Algae, lower, protozoa, are much more primitive in structure - they have no division into organs, and they consist of only one kind of cells. But in these cells complex biochemical processes take place.

Водоросли - это не какие-то вредоносные паразиты, это нормальный член аквариумного сообщества. В большей или меньшей степени они присутствуют в каждом аквариуме. Даже стерилизация всего возможного не гарантирует, что вы сможете избавиться от водорослей. Они попадут туда на листьях растений, а то и просто с водопроводной водой, в которой летом могут содержаться споры простейших водорослей.

Аквариум - модель биосистемы, и водоросли тоже занимают в ней свою нишу. Они - часть естественного баланса.

Green filamentous alga, to a certain extent, is a competitor of plants. If conditions for plants are optimal, they eat well and grow, there is no excess of nutrients and light, then they suppress the algae. If these conditions are violated in some way - the algae “raise their heads”. The appearance of an undesirable resident is an alarming signal that the balance in the aquarium is disturbed, and only by restoring it can you reduce the growth of algae and get rid of them, at least from their excessive presence.

External signs of filamentous algae

"The enemy must be known in person" - this also applies to algae. The fact is that under this name many species are collected, which can often be distinguished only under a microscope. And to deal with them to be different methods.

Here are the main signs by which it is possible to determine with confidence that these are really green filamentous algae.

  • Appearance: thin green threads.
  • Texture: soft, slimy to the touch. When removed from the water, they immediately lose their shape and sag.

The filament is often referred to as a kladofora, but this is a misconception. The cladophora has a hard, elastic texture that practically does not lose shape in the air.

Green filamentous algae feed and grow due to substances dissolved in water and the process of photosynthesis occurring in the light.

Types of filamentous algae and methods of dealing with them

Different types of green filamentous algae have different “preferences” in nutrition and living conditions. To know how to deal with them, you need to be able to distinguish between them.

In the aquarium, there are two varieties of this family: long green threads, freely floating in the water, and shorter, accumulating on the surface of the glass, shoots and planes of plants.

Spirogyra (Spirogura)

Thin, often very long bright green "strands" that can stick together in whole nests. Formed in the vicinity of plants, especially young, which are actively growing.

The difficulty in dealing with spirogyra is that it prefers the same conditions that are good for plants: an adequate amount of nutrients and good light. But a burst of algae growth is usually caused by an overabundance of these factors, even a small one (remember that in optimal conditions, where there is enough, but nothing is in abundance, the plants will suppress the alga, taking nutrients from it).

The rapid growth of spirogyra occurs in well-established aquariums that are not very well cleaned. In this case, the algal surge can be stimulated by some insignificant, at first glance, event: a dead fish that was not seen in time, for example.

Spirogyra threads are very soft, easily rubbed with fingers. They simply remove mechanically - winding green strands on a rough stick made of wood, a toothbrush, and the remains settled on the bottom - siphon. First of all, it is necessary to carry out exactly mechanical cleaning, removing as much algae as possible. Then exclude the factors of its active growth: reduce the light (it is better to darken the aquarium completely for 2-3 days, it will not do any harm to the fish and plants, but for algae it will be a serious blow), slightly increase the water temperature. Replace water more often to reduce the concentration of macro-elements in it. The introduction of the drug bicillin-5 into the aquarium also helps.

There are also natural enemies of this type of algae. She is well eaten by barbs, specials, guppies and other viviparous, shrimps.

Thread (Green Hair Algae, Hair / Thread Algae, Fuzz Algae)

The name brings together a huge number of very similar species. Long strands of bright or dark green, grayish or blackish. They grow in long bunches attached to old plants, stones, bark, filters, on the most lighted places.

With the active growth of algae, after mechanical cleaning, you should pay attention to the composition of water: to establish an even supply of carbon dioxide (CO2 fluctuations accelerate the growth of yarn), to check the concentration of nutrients, the level of nitrates. The reason for the growth spurt can be water pollution with nitrates, ammonium - in this case it is necessary to increase the substitution. It may also be the fault of the deficiency of NO3 and PO4 - plant growth in such conditions is inhibited, and the algae actively come to the fore.

If an additional CO2 supply does not solve the problem - increase the concentration of NO3 and PO4. If this does not help, the excess of macronutrients, nitrates and phosphates is to blame, which should be constantly reduced by changing water, cleaning the aquarium.

Natural enemies of nitrile are viviparous fish, shrimps, barbs, cochlea snails.


Short bright green filamentous algae, appearing in the form of a gun on the leaves and stalks of plants. The first they occupy plants with long stems.

Oedogonium - the first alarming signal about the lack of food in the aquarium, the poverty of the soil substrate. Under normal conditions, this type of algae is easily replaced by strong plants, but with a lack of nutrition, a burst of growth of the “green gun” is possible.

The main mistake that an aquarist can make when he starts to deal with this type of algae is to encourage water changes without introducing additional nutrition for the plants. To eliminate them, you need to check and, with a deficiency, increase the supply of carbon dioxide, feed the plants with macro-elements.

"Green Fluff" will be happy to eat shrimps, mollies, barbs - they will help fight the scourge, but they will not solve the problem completely.

Chlamydomonas and Chlorella. (Green water, Algae bloom, Green tinted water, Euglaena)

"Water blooms" is called the process of rapid growth of these algae. In summer, this happens in all freshwater bodies: the water becomes muddy, green, and thin green threads float in it. The reason: the simplest unicellular algae, actively breeding and freely floating in the water.

And if for natural reservoirs it is a part of the natural life process, then for an aquarium it is a real disaster. Most of all these algae harm the plants, shading them and taking food.

Strictly speaking, unicellular algae are not filamentous - they are even more primitive in structure. However, in aquarium terminology, these species are often combined. The fact is that in the mass single-celled cells can be combined into groups and threads, their texture, growth conditions, damage to the aquarium and methods of control are very similar to filamentous ones.

Flowering water - a sign of over-light and pollution of the aquarium. To cope with this process, it is necessary to shade the aquarium for several days, adjusting at the same time a powerful and smooth operation of the compressor. But even if the algae disappeared from these measures, a water change can cause a new outbreak, and the procedure has to be repeated. Therefore, the only way would be to use a diatom filter or a UV sterilizer.

Chemical method of dealing with unicellulars - bitsillin-5, penicillin. Well helps ozonation of water.

You can get rid of flowering in a natural way - Daphnia crustaceans feed on algae and clean the water for several days. The only problem with this method - from the aquarium will need to remove the fish that Daphnia happy to eat.

Prevention Overview

An “algal disaster” will not come in an aquarium in which the correct balance of life is respected. The appearance of green filamentous algae is, above all, an alarm for the aquarist, indicating the beginning of the inhibition of plants due to an excess of some substances and a shortage of others. To avoid this, follow the simple recommendations.

  • Regular cleaning and changing the water in the aquarium. If these conditions are not met, a lot of decomposition products, nitrates causing rotting, water damage, and algae accumulate in your indoor pond.
  • Harmonious lighting. Excessive light provokes excessive algae activity. For a good control of this factor, it is necessary, first of all, to establish an aquarium correctly, where direct sunlight will not fall on it. The length of daylight, sufficient for plants and fish - 10-12 hours.
  • A sufficient amount of aquarium plants. Algae often begin to actively proliferate where there are few or no plants, in an aquarium with cichlids, for example. These fish are actively digging the ground, and aquarists often decorate their homes only with artificial decorations. Meanwhile, plants are necessary for the harmonious life of an artificial reservoir, otherwise their place in the bio-system will be occupied by uninvited aliens.
  • Good aeration. A sufficient supply of oxygen is necessary for everyone living in the aquarium. If the plants themselves feel good (and they need oxygen), then they will be able to inhibit the growth of algae.

It is important to remember that algae are equal participants in biological processes taking place in your aquarium. It is not their presence at all that is harmful, but their active growth, an excess of algae. In a well-balanced aquarium invasion of algae will not happen.

Many experienced aquarists do not protest at all against the visible presence of algae, specifically leaving them in inconspicuous places. In small quantities, they benefit by absorbing some excess nutrients and rotting products.

An important principle of aquarium maintenance is regularity and moderation. Where the fish are fed, not overfeeding and the volume of water is sufficient for them, the plants live and thrive, the dirt is constantly removed, and the water is refreshed and aerated - in a harmonious, well-kept aquarium there is no “environmental catastrophe”.

How to get rid of flowering aquarium ?? ? my often, but not very good helps…

Yury Balashov

The fight against evulennoy (green water).
1. Complete blackout of the aquarium for several days. (But it is necessary to put the compressor.)
2. Water treatment with a UV lamp.
3. Let the willow branch into the aquarium. As soon as the roots begin to grow on this branch - all the greens will disappear.
4. Land the fish, and run a lot of living daphnia - it will devour all the algae and the water will clear.
5. A bag of activated carbon in the aquarium for several days.
6. Double-molded mollusks, Druza zebra mussel cleans literally in 2-3 hours and forever.
7. Iron vitriol very quickly helps.
8. CHEMISTRY. Pour in Sera Algovec and after 20 minutes the water is clear and enough for 2 weeks.
9. Dimming does not always help for a long time, unfortunately.
10. Do not feed the fish until complete purification of the water.
11. Do not substitute water, fresh water gives the stimulus to reproduction euglena.
12. Wash the filter, only the cat will become clogged.
13. Lighting limit to 6 hours.
In any case, do not forget about the mandatory aeration during flowering, especially at night - euglena in the dark will take out all the oxygen and allow carbonic acid - the fish can die from suffocation.
Patience and good luck.

Why does the water in the aquarium bloom and how to deal with the blooming of water. The process of flowering of water in the aquarium, begins at a time when conditions in the aquarium begin to favor the rapid growth of algae in it. Here it is necessary to clarify that in aquarism, there is a division into directly algae and aquatic plants. And if the last you go to buy at the pet store, then you yourself get the algae in the appendage, besides your desire. These algae are microscopic protozoa, which multiply rapidly and make the water opaque. So, how to get rid of algae in the aquarium, and therefore stop the flowering of water in it?
Method one. If the water in the aquarium blooms, it means that conditions in the aquarium favor the development of algae in the water. One of the main factors of water blooming in an aquarium is a large amount of organic matter in it. In particular, during normal biofiltration in an aquarium, the concentration of nitrates in aquarium water greatly increases. According to personal observations, the bloom of water in the aquarium begins when the concentration of nitrates grows to 30 mg / l and more. Thus, one of the main ways to get rid of the flowering of water in the aquarium is to maintain the concentration of nitrates in it below 30 mg / l.
The second way. In this case, the answer to the question of how to get rid of the flowering of water in an aquarium lies in the technical field. What needs to be done to get rid of the flowering of water in the aquarium in this case? The answer is simple - purchase and install a flow-through UV sterilizer. The fact is that when passing through a UV sterilizer, the water flow is irradiated by a UV lamp, which has a detrimental effect on all life, including algae. Thus, you can install a flow-through UV sterilizer in the aquarium to get rid of the flowering of water in the aquarium. Why precisely flow? - The fact is that the flow-through UV sterilizer can be used to sterilize water in an aquarium populated with aquarium fish and other living creatures, since it does not directly irradiate the aquarium itself, but only the water flow passing through it.
The third way. Reduce the illumination in the aquarium. Usually, the aquarium is completely darkened for several days, it is recommended not to feed the fish in the aquarium. Algae without a source of light and food, die in a few days. The disadvantage of this method is that it helps to get rid of the flowering of water in the aquarium only for a while, then, if you do not take measures to change the conditions in the aquarium, the flowering of water in the aquarium will start again.
The fourth method. In this case, special preparations for controlling algae in the aquarium will help us to get rid of the flowering of water in the aquarium. Preparations to combat the flowering of water in an aquarium inhibit the development of algae in it by chemical means. The downside of this method is that preparations to combat the flowering of water in the aquarium often also affect aquatic plants and invertebrates, which are also in this aquarium.
I hope this article has helped you and answered the question why the water in the aquarium is blooming and how to get rid of the algae in it.

Anna Shipitsyna

may bloom for various reasons:
1. on an aquarium direct sunshine get.
2. Filter or absent or junk.
3. poorly functioning ecosystem as a whole (for example, a lot of food, no live plants)
