My KH has dropped to 6.5. I don't like dosing anything in my tank as I think it'll just lead on to other problems although this Kh level worries me. I only have 2 lps corals and 1 tiny SPS frag so there is not much demand on the system. My calcium is at 420 so this seems fine. Any ideas? And us it true that my calcium levels will fall if I do dose to raise KH?
