Hi, have had a 55 gallon tank for about a year now, never dosed calcium or anything into the tank before. I've just recently begun testing for Magnesium, Alkalinity, and Calcium with red sea pro test kits. I know they are not all supposed to be elevated. Magnesium is at 1560, Alk at 14 Dkh, and Calcium at 490. Any reason they could be so high?
