Test Your Spa Water
Use HTH spa™ Test Strips to test your spa water twice weekly. pH levels should be maintained between 7.2 and 7.8 ppm.
Apply HTH spa™ pH Up
If the pH level measures below 7.2 ppm, apply pH Up directly to the filter skimmer with the spa circulation system running. Refer to the on-pack chart for correct dosage.
