So i was at the lfs last night looking at their brain coral. I asked about its needs and they started piling up additives and food on the counter. One was called Marine Snow and the other was B-Ionic Calcium Buffer and it comes with another bottle i forget what it did , ph fixer or something. Anyway, my question is, has anyone used these products and maybe a suggestion on other products that would suit a brain coral or all corals in general.
