Do for hatching? Fish eggs do not need to change water for hatching. Fish eggs and adults are different, although they all like clean water, but the impact of fluctuations in water quality on them is not the same. Adult fish can adapt to changes in water quality, even if there are large fluctuations, it is only a matter of resting for a while. But the fish eggs are not good, the change of water quality caused by changing water is enough to kill them, so it is strictly forbidden to change water during hatching, only after a week of hatching.
at ordinary times 1. Trapped water: It is necessary to trap water before daily water change. Because household fish farming uses tap water, after disinfection, there will be residual chlorine, which is harmful to the health of fish, so it is necessary to remove chlorine through trapped water. After collecting the water, put it in the sun for a few days.
2. Pumping: Before changing the water, it is necessary to pump out part of the old water in the tank. Water can be pumped by water pump or siphon method, and the pumping place is usually at the bottom of the tank, which can also clean up the residual bait and feces scattered at the bottom, so as to better improve the environment and maintain the water quality.
3. Water injection: After pumping, you can inject water into the fish tank. The temperature of the new water must be the same as that of the old water, so it needs to be adjusted. After that, the new water is slowly poured into the tank from the wall of the tank. Do not change the water with glass, which will cause fluctuations and stimulate the fish.
