How to change water in ecological fish tank

Fish tank is a good ornamental household product, which can beautify the space and bring vitality to the room, but it is not easy to clean the fish tank. Next, PChouse will talk to you about how to change water for the ecological fish tank.

1, it is generally not recommended to change the water in the whole tank for large ecological fish tanks. It should be noted that the whole tank is changed after the fish's illness is cured. In the usual management, we should try to avoid changing the water in the whole tank of the big fish tank. Because the fish has adapted to the water quality in the tank, changing the whole tank will suddenly change the water quality, making it difficult for the fish to adapt, and the original water environment will be destroyed.

2. The water changing capacity of ecological fish tanks should be treated separately according to the species, density and filtration conditions of fish cultured in large fish tanks. When changing water, suck out the dirt at the bottom of the cylinder with a straw and add a proper amount of new water. If there is a fish tank with high fish density, small size and turbid water quality, it may be necessary to filter all day and change more water every time. Some fish have little activity and like old water, so the frequency and quantity of changing water should be reduced.

3. Don't change water directly with tap water. Domestic tap water contains a lot of bleaching powder, which will bring harm to ornamental fish. Boiled tap water can be cooled there and then added to the water tank, so that all harmful bacteria in the water are killed. Another simple method is to connect the water to the container and let it settle for a few days.
