Sorry to revive old thread but trying to mix the magnesium and calcium powders.First of all you should know your daily concumption of Ca, KH and Mg.
Remember to dose Ca, Kh, Mg and Reef Mineral Salt in equal proportions.
I know recipe calls for 50g of calcium and 10g of MG in 1L of Rodi... does anyone know the equivalent of 50g and 10g respectively in Tablespoons etc... ?
