Well I bought a 200g bucket of Oceanic because I ran out of IO. I did a 20% WC with the new salt yesterday. I checked my calcium levels in my DT before and after the wc. I also tested the water that was going in. Before with the IO, the change water was a 440 ppm calcium, after the wc the calcium level would be near 400 ppm. After a two week period when I do my wc's my levels would be at 330ppm. My tank was at 330ppm yesterday. My levels on my change water using Oceanic was 500 ppm, after the wc they were at 485 ppm. I can't believe that, I am dumbfounded. The alkalinity was at 15 dKH.
