? Koi prefer to live in weak alkaline water. The PH value of the water should be controlled between 7.0 and 7.5. However, when we change the water for them, we must pay attention to the use of drying water, the new tap water contains a lot of chlorine, if not treated, it will cause damage to the koi itself, it is best to dry for two days before use. In addition, it is also necessary to maintain the stability of water quality, too alkaline or weak acid water will cause damage to them. If they live in alkaline water for a long time, it will cause damage to their gill fins and increase their risk of poisoning.
? Breeders should pay attention to the following points when changing water for koi:
1. Water temperature: It is better to keep the water temperature constant at about 25 degrees, and the temperature difference should not exceed two degrees each time.
2. PH value: Note that koi is suitable for living in water with a PH value between 7.0 and 7.5. Be careful not to make too big a difference.
3. Hardness: Koi does not have a clear requirement for the hardness of the water, but when changing the water, do not put them directly into the water whose hardness is too different from the old water, otherwise it will cause damage to them.
