Guys, I have this problem with very high KH. KH: 13 CAL: 440 I am using Red Sea salt (normal type, not the pro) and tested the freshly mixed salt to be KH: 8 & CAL 380. Previously I was dripping kalk which explains the increase in KH & CAL, but I've since stopped dripping it for a week. The last I checked before doing a 10% water change, my KH was 11, CAL 400 I dosed Seachem Reef calcium hoping to lower the KH and increase my CAL. Two days later I tested again and my KH increased to 13, CAL was 440. Any idea what can contribute to the increase in KH? I'm stumped. Only other thing I dosed was RedSea Reef Energy A & B, and one tablet of bacteria (which I can't remember the brand). Hope anyone here can help.
