The water circulation fish tank also needs to be changed. No matter how good the water circulation is, it can not achieve the effect of nature, and the water contained in the fish tank itself is very limited, and the significance of repeated circulation is also very limited, so it is still necessary to improve the water quality by changing water. It should be noted that because tap water is used for fish farming at home, chlorine in the water must be volatilized cleanly, otherwise it will threaten the health of fish, and the method of removing chlorine is generally drying.
for changing water in the fish tank? 1. Frequency: First of all, pay attention to the frequency of changing water. If the water is changed too frequently, the new water will stimulate the fish, but not changing the water for a long time will lead to the aging of the water body. Normally, the cycle of water change is related to the maintenance of water quality. It can be changed once or twice a week to ensure that the water is turbid.
2. Amount of water: Usually, the amount of water changed is related to the frequency. If the number of times of water change is large, the amount of water changed each time will be small. If the number of times of water change is small, the amount of water changed each time will be large. However, the amount of water exchanged each time should not exceed one third of the total amount. Too much new water will also stimulate the fish, and more importantly, it will destroy the ecological balance in the tank.
3. Temperature: The temperature before and after the water change must be consistent. If the temperature difference is too large, the fish may have a stress reaction. In order to ensure that the temperature is close, you can measure the water temperature before changing the water, and then mix the new water according to the temperature of the old water.
