About This Item HTH Spa pH Up helps balance pH levels in your spa water improving both water quality and comfort. pH Up not only ensures that your sanitizer is working more efficiently but it helps prevent corrosion of spa surfaces as well as significantly reduces skin and eye irritation. HTH Spa pH Up is great for all spa types including bromine chlorine and biguanide. How To Use HTH Spa pH Up Use HTH Spa Test Strips to test your spa water. If pH measures below 7.2 ppm add HTH Spa pH Up directly to the filter skimmer with the spa circulation system running. Refer to the on pack chart for the correct dosage.
