KH

Question
I keep Malawi Cichlids...My KH is 18, a bit high, but what harm will this do?   (gh 11)  Thank you. Jason

Answer
Hello,

Personally I never tamper with either KH or GH. The biggest concern is your fish. If they look healthy and well, then you should be safe to leave their KH where it is. They have probably adapted to these conditions.

I hope this helps,

Good-luck,
