Dosing instructions
Standalone magnesium supplement (36,000 ppm Mg) — separate from the B-Ionic two-part calcium/alkalinity system. Official: 1 mL raises 1 US gallon by 10 ppm magnesium; dose up to 1.5 mL per gallon per day until magnesium reaches 1200-1350 ppm, then dose to hold. Correct magnesium before chasing calcium and alkalinity. Do not dose in the same spot/time as alkalinity supplements.
