After lurking for a year, I take a bite on this one! If your GH/KH is 0 and your PH is way in the yellow, meaning below 5 you can adjust the GH by adding Epson Salt and Calcium Chloride (Kent Marin-Concentrated liquid Calcium) to the desired level ! You then go ahead and adjust the KH with Potassium Bicarbonate without effecting the GH Make sure the KH is 70% to 80% of the GH Definitely avoid GH = KH or KH bigger then GH or you just go to your LFS and buy Seachems "Equilibrium" 'hope this helps. Prost !
