General Reef Discussion
I'm new at this and blundering along. I have a 12 gallon mini reef which I have over dosed with Calcuim, now 650PPM, and my corals are NOT happy :(
My two fish are fine, as are the anemone, crab, shrimp, snails etc. Just the corals. My salt mix measures 550PPM and water changes do not seem to...
