I have a 75 gallon mixed reef tank with a 20 gallon sump. I reciently started using Reef Fusion 1 and 2. According to the bottle, I should dose around 12 ml each to maintain my calcium and alk levels. When I do this, my calcium level stays at 420. However my alk stays at 7 dkh. I slowly have tried increasing it because my alk is so low. I am up to 30 ml/day. My calcium is still at 420. My alk will rise to 9 dkh, but will drop to 7.8 dkh by the next am. My tank only has softys, a few lps, and a few sps frags. I am using a bubble king skimmer (not sure if this is hurting anything). Does this sound correct to get these fluctions in alk? Or is it ok to have such a low Alk and within range calcium?
