I have a Question do SPS Corals Suck up Calcium that fast 3 days ago i tested my calcium and it was at 500 ppm, the day after i had got 2 new SPS from Walt Smith and Actlimated them. They are doing very well better than i thought as SPS always die on me, Well the next day i tested again and it was at 350 ppm, Then the Day after that it was 300 ppm, Now I cann't get it to go past 300 it just stay there I dose at night and in the morning. I have 9 SPS corals that are in the tank and 2 clams that i have had the clam for 9 months now. Can some one give a answer I may have to get a Calcium reactor or a Kalk Doser. :?
