Dosing requirements will vary, but do not exceed the recommended dose without checking your pH and alkalinity (alkalinity should not exceed 6 meq/L). Use 5 mL for every 80 L (20 US gallons) daily until pH stabilizes to desired level.
pH stabilization may take from a day to a week, depending on original pH, alkalinity, and buffer system balance. Thereafter, use as needed to maintain pH.
