Why is the water green in the aquarium :: the water is green in the aquarium what to do :: Aquarium fish
“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 “flowering”, you need to find out its cause.
The question “opened a pet store. 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-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.
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.
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.
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 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.
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.
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.
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.
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.
For example, algae of the genus Aufwuchs (from German – growing on something), grow on solid substrates, such as rocks, in both fresh and salt water. Algae, especially green and diatoms, are the main habitat for small crustaceans, rotifers, and the simplest forms of life.
A lot of aquarium dwellers intensively feed on surfaces overgrown with algae. Lake Malawi cichlids are widely known as fish adapted for feeding on algae.
Examples of the type, Labeotropheus trewavasae and Pseudotropheus zebra, are very characteristic. They have hard teeth that allow you to tear off algae from rocks. Mollies seek algae glades and pluck them.
In the marine environment, algae are an important part of the nutrition of sea urchins, sea worms and chitons.
I stimulated fouling algae in my tsikhlidnik, to create a natural environment, and got the right amount of nitrica and diatoms. Thus, depending on the species of fish and habitat from the habitat, growing algae may even be desirable. Algae is an essential part of the diet of species such as mollies, African cichlids, some Australian fish, and soma, such as ancistrus or otocyclus.
Frequent water changes reduce the amount of nitrates in the water and reduce the growth of algae. In a well-balanced aquarium richly overgrown with plants, the balance of minerals is in balance, the surplus is consumed by plants and algae.
And since higher plants always consume more nutrients than algae, the growth of the latter is limited.
Located in most aquariums in the form of green dots or green film. These algae love a lot of light.
Green algae grow only if the amount of light and nitrates exceeds the level that higher plants can absorb. In densely planted aquariums, green algae develop extremely poorly, since higher plants consume nutrients and absorb the light necessary for the rapid growth of green algae.
Without condemning the use of plastic plants in an aquarium, I note that living plants look better and create the conditions for the normal development of the entire biosystem.
However, they can massively develop in aquariums with CO2 systems, due to fluctuations in carbon dioxide levels during the day. An outbreak of green algae growth can occur suddenly, especially when the level of phosphates and nitrates in the water is elevated. Usually they look like green dots covering the surface of the glass and the bottom of the aquarium.
The recommended countermeasures are reducing the amount of light and the length of the day, and mechanical cleaning is done with special brushes or a blade.
Mollies and somas, for example, ancistrus, eat green algae very well, and I keep a few specially for this purpose. The snail neretina also copes well with xenococus and other algae.
Green water in the aquarium is obtained due to the rapid reproduction of unicellular algae – euglena green. Manifested as turbidity of water to completely green.
The water loses its transparency, the balance in the aquarium is broken, the fish suffer. As a rule, water blooming occurs in spring, with an increase in the amount of light, and water blooming in natural water bodies, from which we get water.
To combat the flowering of water, you need to reduce the amount of lighting in the aquarium to a minimum; The most effective method is a UV lamp installed in an external filter.
A very effective way to combat the blooming of water is to make a substitution and completely shade the aquarium for 3-4 days (for example, cover with a veil). Plants will survive this.
Fish too. But the water usually stops blooming.
After this, make a substitution.
