Water is blooming in the aquarium

maintenance, care, compatibility

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.

Why does the water bloom in the aquarium :: green water in the aquarium what to do :: Aquarium fish

The flowering of water in an aquarium often begins suddenly. At first, the water becomes slightly cloudy, then becomes green and slightly transparent.

To combat these phenomena, you need to know its nature.

1. The reason for the blooming of water is the mass reproduction of unicellular flagellated microorganisms. Botanists attribute them to algae, zoologists – in part to the simplest animals.

But it will be important for you that all these microorganisms are capable of photosynthesis, that is, light is necessary for their development.

2. It is the excess light that is always indicated as the main cause of water blooming. When installing the aquarium, you must ensure that direct sunlight does not fall on it.

An exception can be made only for spawning aquariums and only for the immediate spawning period, if necessary.

3. The spectral composition of light is also important. Higher plants prefer the “warm” light of incandescent bulbs, while the algae multiply rapidly with the “cold” light of fluorescent lamps.

Use a combination of different light sources and try to choose the illumination so that it is sufficient for the growth of aquarium plants, but no more. It is necessary to light the aquarium from above.

4. For photosynthesis of flagellates, the content of carbon dioxide in water, which is abundantly released by aquarium animals, is of great importance. Higher plants are competitors of flagellates in the absorption of carbon dioxide, but they also release it in the dark.

Ammonia dissolved in water is also a food for flagellates.

5. Be sure to use aeration and filtration of water in the aquarium, and around the clock. Thus, you will create conditions for normal gas exchange, and this, in turn, will reduce the likelihood of water blooming.

Filtration will allow you to get rid of suspended organic residues, which are the nutrient medium for lower organisms, such as euglena – an active participant in the flowering process.

6. If the water in the aquarium has already blossomed, then you will have to fight this phenomenon. A complete change of water will not give results.

The unicellular flagellated chlamydomonads can form drought-resistant spores, and eugleins are cysts. After a while, the aquarium will bloom again.

Better use biological methods to combat flowering.

7. Microorganisms that cause water blooming are the food of many animals. Young tadpoles of a spur frog will clear the aquarium flagellates in a few hours.

If you run the large daphnia Magna in the aquarium, they filter the water for a couple of days, and the fish themselves will eat them later.

8. You can use the mollusks-filter feeders. Bicuspid sharovki reliably clean and protect your aquarium from water bloom if you plant them in a plastic jar with small holes, burned by a needle.

The walls of the banks will protect them from fish.

Do not use snuff or perlovits as filter mollusks in any case. These mollusks infect fish with their larvae – glochidia.

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, water “blooms”, 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 a few days, shade 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 :: 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.

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” exactly 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.

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.
