As Needed: 1. Turn ON air blower or filter system. 2. Add 1 oz. directly into spa. 3. Retest water after 30 minutes. 4. Follow steps 1-3 until pH and total alkalinity are in the range of 7.2-7.8 and 80-120 ppm respectively.
Tips: Add small quantities at a time allowing the water to completely mix and come into equilibrium before retesting. Large dose at once may drive the pH too high. Easier to stay within the pH range when using liquid. Lock in pH between refills with pH Balance or pH Balance Plus.
Compatible With: Chlorine, bromine and biguanide sanitizers.
Advantage: Part of the Leisure Time Simple Spa Care™ program.
