Did a water test today and found that my CA is @ 800, ALK 7.5, PH 8.1 - 8.3, NH3 0, Ites 0. I use Oceanic salt. I dont have any hard corals but do have 2 medium sized polyps and 1 small one. I have over 90 lbs of LR in a 75 gal tank. I guess the real question here is... how to lower CA and raise...
