HTH spa™ pH Down is great for all spa types including bromine, chlorine and biguanide. How To Use HTH spa™ pH Down Use HTH spa™ Test Strips to test your spa water. If pH measures above 7.8 ppm, add HTH™ spa pH Down directly to the filter skimmer with the spa circulation system running. After the spa circulation system has been running for 30 minutes, re-test pH and add more pH Down if necessary. Test and balance your spa water twice a week to maintain pH levels between 7.2 and 7.8 ppm.
