fish tank turns white, the water should be changed first. Changing water is an essential step in the process of fish farming, which can greatly improve the water quality, usually every five to seven days. Water should not be changed too frequently, if the water is changed every day, the water quality will fluctuate greatly, which is also a kind of harm to fish. In addition, attention should be paid to the amount of water exchanged, usually each time the amount of water exchanged does not exceed one third of the total amount of water, about one fifth of it.
In order to improve water quality, a device is needed to maintain water quality continuously, which is the filter. There are many kinds of filters, such as bottom filter, upper filter, filter barrel and so on. According to the situation of the fish tank, it is very important to choose the appropriate filter. In addition, the flow of filtration is also critical, if the water circulation is too slow, the filtration effect is poor, so it is necessary to ensure that the fish tank water can be circulated about 7-10 times per hour. Filter materials should also be comprehensive, including filter cotton, activated carbon, bacterial house, etc.
feeding fish needs to feed it, but if you feed too much, it will also make the water white. In view of this situation, it is necessary to stop feeding for a period of time, and then resume feeding after the water body is restored, but the amount of feeding should be reduced. It can usually be fed two or three times a day, so that a small number of times can avoid the deterioration of water quality. Each feeding should let the fish eat within 3-5 minutes, can not feed too much, water turbidity will not only affect the viewing, but also cause the fish to get sick.
