Green algae on the walls of the aquarium

maintenance, care, compatibility

If you find a patina of green color in an aquarium, then first of all you should pay attention to caring for it. If you do not clean and change water in time, then sooner or later you will definitely encounter a green tint of water and walls.

This state of affairs can be deadly for the inhabitants.

Measures to clean the aquarium from green algae:

  • Reduce the light intensity. Green algae grow favorably with excessive light, so limit the backlight time to 10 hours per day. Avoid direct sunlight, from which the water becomes even greener.
  • Daily replacement of 15% water. Of course, this process will take a lot of time, but it is necessary to do so in order to preserve the ecosystem in a neglected aquarium. Water suited for this purpose is suitable for this.

After the algae visually disappeared, it is necessary to take measures to eliminate the source of water infection. The presence of plants will help you protect your body of water from uninvited “guests.”

It has been proven that the presence of flora favorably affects the cleanliness of the aquarium and the algae do not settle on the walls, decor, plants and soil. From this it follows that it is necessary to settle as many plants as possible, which will protect aqua.

It happens that algae go into the active phase even with a large number of plants. This suggests that the flora is in a disgusting state. Most often this means that the plants do not receive the necessary trace elements.

The first nutrient deficiency causes insufficient nutrition. That is why experienced aquarists know how important it is to apply fertilizer to the soil.

Be careful when choosing a fertilizer. Since in the struggle for the popularity of zoological fish, many manufacturers proudly declare the absence of nitrates and phosphates in their products.

Thus, they are trying to convey that they have excluded those products that cause the growth of algae. But, on the other hand, these macronutrients are incredibly important for maintaining harmony in the ecosystem. Most novice breeders diligently choose phosphate-free products and only make things worse, without knowing it.

In fact, nitrates and phosphates are the main food for plants.

If you believe the statistics, then more than 80% of the problems associated with the lack of these elements. Unfortunately, this can only be learned in a critical situation, when plants stop growing, and algae overwhelm all the space, walls, soil and scenery begin to sink in a green patina.

Green plaque that forms on the walls is called xenokakus. Because of it, the walls and decorations are covered with an unpleasant shade.

Xenokocus multiplies under the influence of excess light, so most often this problem occurs in aquariums with excessive lighting. Limit light output to 5 watts per liter of water.

The second most important reason can be considered a lack of oxygen or more jumps in performance during the day. If this is not your first time encountering this problem, then consider buying an H type controller.

However, it is hardly possible to protect oneself from this phenomenon forever, but it is quite realistic to slow down.

Prevention in the appearance of green plaque:

  • Oxygen regulation;
  • Lighting limit up to 8 hours;
  • Decrease light intensity;
  • Establishment of snails of theodox, fiz, coils, antsistrusov and otozinclyus

To resort to chemical means to clean the aquarium is not recommended only if the situation becomes threatening to all inhabitants.

Owners of aquariums are often faced with such a problem as blue-green algae, which are actively growing in their small artificial pond. As soon as such a colony appears on the walls of the aquarium, the alarm should be sounded.

This is a marker indicating a violation of the ecological balance that must be dealt with.

Scientists refer to the blue-green algae to the class of bacteria. In appearance, they resemble a mucous carpet on the surface of an artificial reservoir of a dirty brown color. Such living forms have exceptional adaptability and vitality.

If the blue-green alga started up in an aquarium, then it will be difficult to get rid of it.

If you give a precise definition, it is cyanobacteria that appear on the walls of the aquarium when it is exposed to prolonged exposure to direct sunlight, or when the water temperature is higher than is required. Also beneficial to the development of blue-green is a large amount of organic impurities. Such bacteria quickly begin to develop if the aquarium is not regularly cleaned.

Also, the cause of cyanobacteria is a rare change of water in the aquarium.

Blue-green algae is very unpretentious, they have enough minimum conditions for development. These bacteria take all the nutrients necessary for their development and growth out of the water.

They grow not only on the ground, but also on any object that may be at the bottom of the aquarium: stones, snags, shells. The unique ability to restore quickly allows blue-green algae to quickly restore its population.

Therefore, to get rid of them is not so easy.

The peculiarity of these microorganisms living in the aquarium is an unpleasant odor. The greater the surface of the artificial pond covers the blue-green alga, the more polluted the water becomes, and the aquarium itself turns into a decaying puddle.

The detrimental effect of blue-green algae on the artificial microclimate of an aquarium is that they prevent water from dissolving oxygen, increasing the amount of nitrogen in it. Getting rid of such bacteria is not easy.

There is a special way to deal with blue-green algae that every aquarist should know.

The simplest and most common way to deal with blue-green algae is to darken the aquarium. To do this, remove from the aquarium fish, plants, stones and snags, compressor, filters and other equipment.

After that, it is closed from the light for three days. During this time, carbon dioxide ceases to enter into water, which is emitted by blue-green algae.

In the absence of light, such a bacterium will die in three days.

The danger of this method of cleaning is that the soil can remain microscopic particles of such algae, which after a short time will again develop into a huge colony. Blackout aquarium should be combined with disinfection of an artificial reservoir.

Only in this case it is possible to defend more reliably, which helps to further deal with the problem.


Successful wrestling involves disinfecting aquarium equipment from blue-green algae. It must be thoroughly boiled, so that the smallest residues of cyanobacteria are destroyed.

To completely remove the blue-green algae and plants in the aquarium, you need to put them in a weak solution of potassium permanganate for at least half an hour. Then the aquarium vegetation is washed in running water and transplanted into clean water.

Themselves fish, snails, mollusks and all other living organisms living in the aquarium, are also deposited in the settled water for several days. Having arranged such a quarantine to all living things in an aquarium, you can clean it well from microorganisms. In the reservoir of the net, the remains of blue-green algae are caught.

After that you need to handle the soil of an artificial reservoir with the help of a compressor. It is necessary to siphon soil so that it is enriched with oxygen.

Remote living organisms in the form of fish, newts, snails, plants and accessories begin to return to the cleaned tank. First, they are planted in the ground from the quarantine capacity of the plant.

They must acclimatize during the day. Therefore, they should be left in the tank for a day.

Such a daily quarantine in the aquarium itself allows you to make sure that you managed to get rid of the blue-green algae on the plants. During planting and acclimatization of aquatic plants, it is necessary to protect the artificial reservoir from direct sunlight in order not to create a favorable environment for these microorganisms.

A day later, a fireplace, shells and other accessories return to the glass pond, allowing you to create the desired design. They are also left for a day to check whether cyanobacteria are left on their surface.

Only after daily checking of such accessories can you run fish and other inhabitants of the underwater environment at the last stage.

See how to effectively clean the walls of the aquarium from the blue-green algae.

The advantages of combining the method of darkening and adding peroxide to water

Using the technique of darkening and adding hydrogen peroxide to aquarium water allows for a good cleaning of its walls from blue-green algae. Using the combined disinfection of an artificial reservoir will help save it from cyanobacterial infection.

In general, the most effective means of combating blue-green algae is the prevention and regular cleaning of an artificial reservoir. This will avoid the accumulation of organic sediments in the soil of the aquarium, from which cyanobacteria will be fed.

You must also ensure that the walls of the tank did not fall into direct sunlight. In general, the lighting of an artificial reservoir should be moderate.

It is also necessary to ensure that water does not accumulate a lot of carbon dioxide, and oxygen is regularly supplied to the aquarium water.

You also need to clean live food before giving it to underwater inhabitants. This will help to reduce the sources of pollution of the artificial reservoir.

All this will help avoid the appearance of blue-green algae in your tank. Compliance with the rules of hygiene will reliably protect against dangerous microorganisms that create a nutrient medium in the aquarium for blue-green algae.

How to get rid of algae in the aquarium :: green algae on the walls of the aquarium :: Care and nurture

The beauty of the aquarium can be spoiled by rapid growth. seaweed. Water acquires a green color, sometimes becomes cloudy, and the walls of the aquarium, plants and stones overgrow with unsightly bloom or dirty filaments.

Completely remove algae in aquarium It is impossible, but if appropriate measures are taken in time, their growth can be limited.

The question “How does a little girl retrain to go to the tray (she is 4 months old)? “- 3 answers

1. Blue-green algae in aquarium grow under heavy lighting. Therefore, the fight against them should begin with a decrease in daylight hours to 8 hours, the complete replacement of natural light to artificial.

Brown algae, on the contrary, like low light, and it is necessary to fight them by increasing the intensity of the lamps.

2. It is important to ensure that the fish eat the entire food, as rotting debris only contributes to the nutrition and undesirable growth of lower plants.

3. You can put competitors in the aquarium seaweed – Higher fast-growing plants and create good conditions for their growth, and reduce the number of fish for a while. At the same time replace every day a tenth of the water and clean the soil.

4. There are fish that feed on algae, for example, Siamese or Chinese algae, ototsinklyus, flying chanterelles, somatos, plecostomy. Even live bears, such as mollies and patrons of the arts, actively eat thread-like fouling.

5. Daphnia algae will also be destroyed, but before they are launched into the aquarium, all fish must be temporarily removed.

6. Reduce the amount seaweed at aquarium coil snails and ampouleries. So that they can fully restrain growth seaweed, you need to have a huge amount of them, and it is not aesthetically pleasing for the appearance.

7. Chemical aquarium treatment is very effective. There are many drugs that are aimed at the destruction seaweed, but after some time the algae will begin to seize the aquarium again, appearing from the surviving spores.

In addition, some plants do not withstand chemical poisoning and die.

8. A laborious, but safe method of dealing with some algae is their manual removal: scraping the walls with a scraper or winding long threads on a stick.
