Solbby, is the Mg that is used taken from the water column or from food?

If you are using MgCl and MgSO4 to raise Mg levels, you shouldn't use the formula that Randy uses in conjunction with his two part. You should use 7 1/4 cups of MgCl to , I believe, 1 3/4 cups MgSO4 to a gallon of water. The Mg formulation when used with the 2 part is balanced when used with the two part, otherwise, it's unbalanced.

I'm slowly trying to raise one sys to the "Italian" levels 1500 Mg, 500 Ca, 10-11 dKH, do we'll see how that goes with sps....
