? If you want to change the water in the fish tank without affecting the fish, you need to extend the water change cycle and reduce the amount of water, so that the fish will not feel it. However, it should be noted that the purpose of changing water is to improve water quality, so as to protect the health of fish, so it is normal to have an impact on fish, as long as the impact is not significant. Moreover, the stimulation of new water to fish is also beneficial, which can promote the growth of fish.
safely in a fish tank 1. Trapped water in advance: If you want to change water safely, you must first trap water in advance. If the water is changed without treatment, the chlorine in the water will endanger the health of the fish. There are generally two ways to trap water, the more commonly used is the drying method, which takes 1-3 days. The other is aeration, which is more efficient, but requires an oxygen pump to complete.
2. Pump water and inject water: Generally, the water should be pumped first. After the old water in the tank is pumped out, the water can be injected into it. Be careful not to suck the fish away when pumping water. It's better to clean up the dirty things at the bottom of the tank. When filling water, do not pour it in directly, but slowly pour it in from the wall of the cylinder.
3. Control the water temperature: In order to avoid the fish being stimulated during the water change, it is also necessary to control the water temperature. The difference before and after should not exceed 2 ℃, and it is better to keep consistent. Usually, the temperature of the old water is measured first, and then the new water is mixed with hot or cold water to adjust the water temperature, so that the temperature of the two tends to be the same.
