The transparency of water, the absence of impurities, the absence of odor are necessary conditions for the normal maintenance of aquarium fish. First of all, the water intended for the aquarium needs to stand for 2-3 days, for this enameled or glassware is best. This is done so that air bubbles that are poorly absorbed by fish dissolve, chlorine evaporates, and iron precipitates.
In order not to wash out the aquarium soil, water through a hose is poured into the aquarium from the vessel located above the aquarium. To the upper edge of the aquarium, about 3 cm. Water is not added.
To prevent dust and water evaporation, the aquarium is closed with glass. In addition, we must remember that it is possible to jump fish out of the aquarium.
Often with prolonged topping up of water, instead of evaporated, a white coating forms on the aquarium walls and plants. This indicates the precipitation of salts. In this case, the aquarium is cleaned by removing salts from the walls and leaves of plants or replacing part of the water with boiled water.
It must be remembered that the frequent change of water in the aquarium leads to a physiological shock of plants (for example, an alternapter), plants drop leaves.
Some types of fish (kopeyna, black barbus, parsing) die in freshly prepared water. These fish love the water in which other fish lived. Therefore, it is recommended to keep unpretentious fish at the beginning: a swordsman, guppy, macropod, gourami, black-striped cichloma, etc.
Quite often, “blooming water” occurs in the aquarium. This is a common phenomenon in which unicellular green algae multiply intensively in the aquarium. In order to prevent this or get rid of flowering, you must:
- Prevent sunlight from entering the aquarium by constantly blowing water.
- Dip a piece of copper wire into the aquarium.
- Remove fish from the aquarium and run Daphnia crustaceans for 3-5 days.
If there is clouding of the water in the aquarium, it is necessary to add light and remove residual feed. However, it must be remembered that the organic remains of aquarium plants after colonization often rot, but after 4-6 days, biological equilibrium sets in, the water becomes clean, and then fish are launched into the aquarium.
Sometimes the water in the aquarium turns yellow. This is the result of abundant feeding, in which not eaten food settles to the bottom and decomposes. A dead fish that was not immediately found could also cause yellowing of the water.
In order to avoid yellowing of water in the future, it is necessary to remove the remains of uneaten feed, regularly change part of the water to fresh, blow water daily with air, to improve water circulation, replace shallow soil with a larger one.
If the water is not satisfactorily flushed in the aquarium, a film may form on the surface of the water, which can be easily removed with a sheet of white paper that is laid on the surface of the water, the film adheres to the paper, and then is removed along with the paper. Often when painting the frame of the aquarium with nitro paint, a film can also form on the surface of the water. In this case, time is required, sometimes up to 2-3 weeks, after which the film disappears.
