I read in Tom Barr's EI article and Watson strategy that the CaCl2 does not dissolve that well in water. Well, it sure does not. Does anyone have any tips on dissolving this stuff? I also read about using GH Booster, but how much of this stuff do you need to bring KH and GH up by a 1 degree at a time? I have soft water and wanted to know how much Ca and MgSO4 I need to raise my levels.
