Sparkypn Posted May 7, 2006 Author Report Share Posted May 7, 2006 sorry. yes knew I had asked about the carbonate hardness before was more the general hardness I was wondering about. Our tank has kh of 10 but our gh is very high over 25 Quote Link to comment Share on other sites More sharing options...
lduncan Posted May 7, 2006 Report Share Posted May 7, 2006 Don't worry about GH. Carbonate hardness is the thing to look at. GH is not particularly important as reef keepers monitor magnesium and calcium independently. Layton Quote Link to comment Share on other sites More sharing options...
