pH Up is used to raise the pH in hot tub and spa water. The water in your spa should be maintained at a pH of 7.2-7.8 ppm (parts per million) and the total alkalinity should be maintained at a level of 80-140 ppm.
Test spa water frequently with a suitable spa water test kit to ensure proper pH is maintained. Spa pH Increaser is compatible with all sanitizers including bromine, chlorine and biguanide.
pH Up Directions for UsepH Up should be used if pH is below 7.2.
Turn on air blower, jets, or filter system.
Add one ounce of pH Up for every 100 gallons of spa water.
Retest spa water after 30 minutes.
Follow steps 1-3 until the pH and total alkalinity are in the range of 7.2-7.8 and 80-140 ppm respectively.
Note: Always wait 30 minutes between doses and test water before each addition of pH Up.
