Second, after pumping water to prepare new water, you can start changing water. First, pump the old water out of the tank. You can pump it with a water pump, or you can find a pipe to pump it out with the help of a siphon. Don't smoke too much, usually change it to one fifth. After pumping out the old water, slowly pour in the prepared new water from the cylinder wall. Be careful not to pour all the water at once to avoid water quality fluctuation.
Thirdly, there is usually no fixed cycle for changing water, because the size and feeding density of fish tanks are different, so the water quality maintenance is not consistent. If the water quality deteriorates rapidly, it should be changed every three days, but the amount of water changed is less. If the water quality deteriorates slowly, it can be changed once every half month, and at most it can be changed by about one third.
Fourth, precautions should pay attention to the change of water temperature when changing water. Temperature has a great influence on fish. If it is not well controlled, the fish may have some stress reactions. Usually, the water temperature should be measured before changing water, and then the temperature of fresh water should be adjusted according to the water in the fish tank to make them consistent, thus reducing the impact on fish.
