Does Koi like hard water or soft water, new water or old water?

Koi prefer soft water with lower hardness. They do not require high water hardness and can survive in both soft and hard water. However, in comparison, they prefer softer water, and it is recommended to keep the hardness of the water between 6 and 8 when raising them. In addition to hardness, they also need to pay attention to the acidity and alkalinity of water. They prefer slightly alkaline water and can be raised with a pH between 7.2 and 8.0.
