Ok everyone here I go again. Last week I finally got my Calcium and alkalinity where I want them. I wouldnt quite say that its stable but I know what to add everyday to keep it where I want it. My target is calcium 440 and alkalinity 11. However every morning the calcium is down to 400 and alkalinity is at 8. So what I have to dose is ESV 3oz part 1 and 5.5oz part 2. Is this normal or am I doing something wrong? This is not going to last long I dont think. Today or tomorrow I think Im going to start dripping limewater and withing the next week or so im going to set up a calcium reactor. My tank is by far nowhere near stocked. Good coraline algae growth, a couple polyps and one really small galexea frag. Thanks for the help.
