I've been thinking about my need for a gh booster, as my tap gh is 1. I looked at GLA's "GH booster" fert package, which had potassion, calcium, and magnesium sulfate. All which I have (in the form of CSM+B, albeit). Can I use these to raise the GH of my tap water during water changes? What do shrimp products use? How much should I use and how will this effect my dosing?
