Even inexperienced aquarists know that if the water in the aquarium turns green, it is a signal of trouble. Such a nuisance can be triggered by various factors and adversely affect the health and longevity of the inhabitants of the aquatic environment.
For this reason, every person whose home is decorated with a “living corner” is required to know how to deal with the flowering of the reservoir. Those for whom aquaria is a longtime hobby or a means of earning, know that the blooming water is not always considered an indicator of poor maintenance of the reservoir and its untimely cleaning, sometimes a greenish tint appears almost immediately after a fluid change.
There are many reasons for this phenomenon, and before deciding how to deal with the scourge at home, you will need to find out why the water in the aquarium is turning green.
Since plants are considered to be one of the main causes of water blooming, for many inexperienced owners of aquariums, the appearance of duckweed on the surface of an aquarium, in which hydrophytes do not live, causes a stupor. Green water in an aquarium without plants is a signal, if not for cleaning the fish, then definitely to replace the filter or its parts.
Microorganisms are deposited in the tube and underwater mounts, creating rotting and fetid odor of water.
There can be many reasons for greening and usually they are caused by the inexperience of aquarists.
The name of these single-celled algae speaks for itself and is perfectly familiar to people who have long been breeding ornamental fish. Euglena forms the thinnest film on the water surface and is an important link in the food chain.
Under poor lighting, the green body of the euglene becomes colorless: the alga visibly fades or loses its color completely.. Mass reproduction, leading to increased flowering of water, occurs when:
- intense lighting;
- the excess in water of organic components;
- failure of aquarium filters.
Euglena bloom can be very stormy: just yesterday the water was absolutely clear, and today it has acquired a dull green shade.
The provocateurs of greening aquarium water are also considered:
- unnecessarily frequent maintenance of the tank (water purification, renewal / aeration);
- poor maintenance of the aquarium (lack of a compressor, insufficient aeration, rotten water);
- increased water temperature;
- a huge number of planted plants;
- the accumulation of chemicals in water (organic substances);
- the wrong mode of lighting (more than 10-12 hours per day) or direct sunlight directed at the aquarium.
Important! Beginners lovers of ornamental fish make another common mistake, feeding them without taking into account the natural needs.
Fish do not have time to completely eat food, and it sinks to the bottom, where it rots, contributing to the greening of water.
It is possible to return the water to the eye-pleasing transparency in various ways, including by resorting to the help of natural cleaners.
Run into the aquarium so many live daphnids that the fish could not eat them immediately. These plankton crustaceans will easily cope with the surplus of unicellular algae that breed in the “fish house”.
Settle in it “lodgers”, whose main food is considered to be algae: fish (catfish, mollies, placium) and snails.
Find a small pemphigus and a robee (aquarium), which, due to their accelerated growth, absorb the excess nitrogen accumulated in water (a flowering catalyst). So, a honefoot for a week is able to stretch by 1.5 meters.
Preliminarily remove humus from the bottom, replace 1/2 of the water and only then place the plants in the aquarium.
First, check the operation of the aquarium equipment to ensure there are no problems. It may be worthwhile to acquire additional devices for water clarification, such as:
- UV sterilizer that regulates algae reproduction by directed ultraviolet rays;
- diatomaceous filter – due to the special filtering composition, it retains contaminants and suspended elements, measured in microns.
Mechanical cleaning methods can be combined / mixed with chemical methods.
The operation of the aquarium filter will become more productive if you put activated carbon (granules) in it. In the process of getting rid of green water, the filter itself is cleaned 1-2 times a week.
It is interesting! Another tried remedy is powdered (pounded) streptomycin diluted in water. Per liter of aquarium water enough 3 ml of solution.
This dosage does not affect the fish, but it fights well with the growth of single-celled algae.
It does not hurt to get a coagulant “Hyacinth”, created for the purification of drinking water, but extremely useful in aquarism. On the manufacturer’s website, it costs 55 hryvnia, which corresponds to 117 Russian rubles. The drug is tested in action.
It turned out that its active formula is capable of neutralizing both organic and inorganic harmful impurities.
Consider that the deterioration of the aquatic balance is bad for the health of all aquarium guests.
Manipulations for water purification should be accompanied by parallel activities:
- if the fish are healthy, move them temporarily to other containers with a similar composition of water;
- place the plants in temporary containers by mixing methylene blue in water (dosage according to the instructions);
- if necessary, replace the old soil with a new one (pre-treated for parasites);
- Pour out old water, fill the aquarium with water with the addition of baking soda (1-2 tsp.) and leave for a day;
- Scald / boil all artificial decorations, including grottoes, snags and shells.
If the fight against greening is not radical and the fish remain in the aquarium, only a third of the water is usually changed to fresh.
When regular cleaning and changing lighting does not improve the situation in the aquarium, liquids and tablets are used based on substances that inhibit the growth of bacteria and algae on the surface of the water. Manufacturers of such products know what to do if the water in the aquarium turns green quickly: they add humic substances to the preparations that fight the film and turbidity in a natural way. They can be identified by the presence of such components as:
After cleaning by one of these methods, preventive measures will be required to maintain a normal microclimate in the aquarium. It is necessary that the water does not bloom.
It is not difficult to achieve this, it is enough to follow simple recommendations: install the container so that it does not fall into direct sunlight; when laying the soil place the content with an inclination, laying a more dense layer of pebbles to the front wall of the tank; adjust the backlight power at the rate of 0.5 W per 1 liter of content; periodically turn off the light, and the algae will not grow so actively (many species of underwater plants can do without artificial light for 5-7 days in a row); cover the tank to prevent particles, dust, insects and debris from entering the water; to control the work of aquarium equipment; clean container, decorative elements and replace water regularly.
These actions do not eliminate the need to periodically replace the contents of the aquarium, but will help to contain the growth of the bacterial environment, and the water will not become muddy and green too quickly. Like any pets, fish require competent care and maintenance of cleanliness in their habitats.
The peculiarity of the underwater inhabitants is that they spend their whole lives in the same container, and for their comfortable existence they will need to carefully monitor the microclimate of the underwater world. Otherwise, the inhabitants of the artificial reservoir will be sick and die prematurely.
