    My calcium seems too be going down rather than up. Right now my calcium is at 230, and I have never been able to go higher than 300. I have used Kent Liquid calcium, and have tried a two part calcium and alk. I have used a whole bottle of the liquid calcium over a two week time frame but my calcium never really gets above 260.

    That is a very odd problem. So you have four foot tall acropora in your tank right? What kind of filtration are you running. Think I read somewhere the wrong skimmer settings will take some calcium out.

    If your mag isnt high enough it will allow more calcium to evaporate.
