I seem to have a problem getting my calcium over 340 I have been adding Kent Kalk daily for a week and it hasnt budged a bit. I tested the Kalk and it was at 600 or so. SO my question is I read that the alk plays a major role in the amount of calcium available. I tested my alk (with a hagen test kit) which reads in ppm
which was 170 I believe the conversion is like 10dKH is this a good level to raise Ca at? I also add Kent Liquid Calcium daily as well.. All this and only three corals. Any advice to get my Ca up? Thanks
