I do a 3 part dosing from BRS with soda ash for alkalinity, calcium chloride, and magnesium sulfate. My alkanlinity and calcium have always been stable at 8.9-9.0 for alkalinity and 440-450 for calcium (using Hannah Checker for alkalinity and Salifert test for calcium.) My Mg is also stable, but that is sitting at 1,500. My alkalinity I'm dosing 58 ml of soda ash per day, for calcium chloride, I'm dosing 35 ml per day, and for Mg, I'm dosing 1 ml once per week. Does this seem odd that my tank effectively isn't using any Mg?
