Ok got my doser setup to dose Calcium and Alkalinity but have a question about magnesium. J&L sell Magnesium Chloride or Magnesium Chloride Flake. The two are the same thing just in different form, so why is here a price difference between the two? Do you have to weigh the flake? or can it be measured? Does the flake dissolve as well as the powder? Is the price difference worth it? Thanks all.
