If you only keep tap water overnight, it is not up to the standard for raising fish. The residual chlorine in the water does not scatter light, and it will still cause certain harm to the fish. Generally, in summer, it is necessary to dry the water for one day, in spring and autumn, it is necessary to dry for two days, and in winter, the temperature is low, it needs to dry for more than three days. The water treated in this way is more suitable for fish farming.
1. Temperature: You must pay attention to the temperature of the water for fish farming. Except for some fish with a wide range of temperatures, such as brocade carp and goldfish, they have a relatively wide range of adaptations to temperature. As long as the water temperature is not very high or very low, these fish can survive. But the situation of tropical fish is different, we must ensure that the temperature is between 20-30 degrees Celsius, some of the more delicate varieties, or even more accurate to maintain the water temperature, so as to keep alive.
2. Hardness: Different fish have different requirements for water hardness. This mainly depends on whether the environment in which it lives is soft water or hard water. The method of adjusting water hardness is soft water resin and coral sand, but generally speaking, there is no need to deliberately adjust, as long as the fish adapt to such hardness, there is no need to change.
3. Ph: Fish also have certain requirements for the pH of the water body. However, neutral water can basically adapt to it. As long as fish that are suitable for living in weakly acidic water are not raised in alkaline water, there will be no problem.
