If I am using BRS two part for calcium and alkalinity and doing water changes every two weeks. I suppose I don't need the magnesium mix if my magnesium levels are steady and replenished every two weeks. I dose like 25 mL per day of alkalinity and 40 mL per day of calcium. So one gallon will last me a LONG time while I get all the magnesium i need from water changes. Is this correct?
Also is it odd i'm using more calcium than alkalinity? I thought it's supposed to be the other way around.
