How to use:
1. One capful hold approximately 1 oz.
2. Test water daily for pH and bromine/chlorine. Add 1 oz. of pH PLUS per 250 gallons of water if testing shows pH is low.
3. pH PLUS is readily soluble in water. It may be broadcast on the spa/hot tub surface. It requires one hour to determine if pH is within recommended range. Repeat if necessary.
