? Generally, fish raised in tap water will not die, but it will have a greater impact on their health. Tap water is processed and disinfected by waterworks, which is not polluted, but after processing, a small amount of residual chlorine often remains. If you want to remove it, you'd better dry the water for a few days, or use an oxygen pump to aerate the water, which can also accelerate the volatilization of chlorine. If the treatment capacity is very large, it is better to use chlorine remover.
should we pay attention to when changing water for fish farming? 1. Trapped water in advance: The first thing to do when changing water is to trap water in advance. The reason for trapped water, as mentioned above, is to remove chlorine. Trapped water usually uses the method of drying, different seasons have different requirements for drying time, usually one to three days.
2. Water change method: Usually, the water needs to be pumped first. Prepare a water pump to pump out the water in the tank, or use a pipe to pump out the water by siphon. Generally, a quarter of the water should be pumped, and then the water can be injected. The trapped new water can be slowly poured into the fish tank from the wall of the tank.
3. Water temperature change: In order to avoid the temperature fluctuation when changing water, which will stimulate the fish, the water temperature should be measured before changing water, and then the new water should be adjusted according to this temperature to ensure that the temperature of the new water is close to that of the old water, and the fish will not feel uncomfortable after changing water.
