Hi toddziegler,I cant remember the formula for adding gh to my ro/di water. All I can remember 3, 3, or 3, 3, 2 can anyone jolt my memory
Obviously, if your sources of Ca and Mg are different, the amounts of chemicals would change. As for potassium (K) there is approximately 3X the amount of potassium than Ca. I used to mix my own GH booster, but now I buy just buy a good mix. I like Seachem Equilibrium because in addition to K, Ca, and Mg it contains Fe and Mn.
