Is to fish? Fish tank water purifier is harmful to fish. The main components of the water purifying agent are polyaluminum chloride, polyaluminum ferric chloride, aluminum sulfate and ferrous sulfate, which can agglomerate impurities in water and then precipitate to the bottom of the water, thus improving the water quality. However, it can not really decompose impurities, and stimulate the skin and mucosa of fish, long-term use will also lead to gill blockage.
1. Change water regularly: The best way to improve water quality is to change water regularly. Usually the water should be changed once a week, if the filtration effect in the fish tank is better, it can also postpone the cycle of changing water, and it is no problem to change it once a half month. The amount of water changed each time should not be too large, otherwise it will destroy the original ecosystem and be harmful to the health of fish.
2. Reduce feeding: The reason why the water quality deteriorates is that the water body is too fat, and the main source of organic matter in the water is the fish food. Whether the residual bait is eaten or the excrement is digested and discharged, it will pollute the water quality. Therefore, it is necessary to reduce the amount of feeding from the source.
3. Prevent algae explosion: If the fish tank explodes algae, the water quality will deteriorate rapidly. In order to prevent algae explosion, we should not only control the amount of organic matter in water, but also avoid light. The growth of algae still needs a certain amount of sunlight.
