16 oz (.4535 kg) SpaPure pH Up for Spas & Hot Tubs
HOW pH UP WORKS:
pH Up is used for raising the pH of spa and hot tub water. The ideal pH of spa and hot tub water is between 7.2 and 7.6. If a test kit reading indicates that the pH is less that 7.2, you will probably experience itchy skin and eye irritations. When used to maintain proper pH levels, this product eliminates eye irritation, chlorine odor and corrosion caused from low pH
DIRECTIONS FOR USE:
This product should be used on an as needed basis to maintain proper pH. If a test kit reading indicates that the pH is less than 7.2, sprinkle 2 1/4 teaspoons of pH Up directly into spa for every 500 gallons. Wait 2 hours and test again. If still low, continue adding. If pH reading is above 7.6, add pH Down per label directions.
Maintain continuous circulation, distribute required amount in the middle of the spa or in front of a jet.
