So I just tested my calcium lvl about an hour or so ago....and it's right at 500.... :-( I haven't dosed calcium or anything since I just got my calc test kit....it's a seachem Btw.....ran the calibration test first and it was right on....tested my water twice and same reading.....any ideas.....I wouldn't think it would actually hurt anything at the moment....but I know it's not in optimum range
