 how high does ur mag lvls have to be till toxic
the first time i tested my mag lvls it was 2350 ppm, second time after a 25% water (with reefcrystals ) change it was 1700 ppm, third time after another 25% water change with (oceanic saltmix) it was back to 2300ppm. i did all my test with salifert mag test kit.
so my question is, is 2300ppm a toxic lvl of mag to coral, and if so why hasn't it killed my hair algea ? |
