CATDOLL : CATDOLL: Why is the water in my koi fish tank always murky?

The water for fish farming needs to be left for seven days before changing the water. Sometimes the water quality is not good and the water will become turbid. Sometimes the fish are sick with bacteria and the water will become turbid. If you change the water frequently and the water is still turbid, you need to use some fish medicine. Using some "super clear" will improve the water quality. And you don't need to change the water for a long time. Sometimes you don't need to change the water for up to a month with super clear water!
