Does anyone have concerns over the rise in sulfate when adding epsom salt (MgSO4) to bring up Mg? I think some of the hobby Mg additives may also be mainly MgSO4. For people doing a 1100 to 1400 Mg bump with epsom salts, you could be getting a dramatic rise (44%) in SO4 levels. Magnesium Supplements, RH Farley
