HTH Spa pH up, Increases pH for Spas & Hot Tubs, Powder, 2lb

HTH Spa Care pH-Up increases pH level and prevents corrosion in Spas and Hot Tubs.

HTH® Spa pH-Up(Increaser) helps balance how acidic or basic your spa water is, improving both water quality and comfort. pH-Up(Increaser) 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(Increaser) is great for all spa types including bromine, chlorine and biguanide.

How To Use HTH® Spa pH-Up(Increaser): Use HTH® Spa Test Strips to test your spa water. If pH measures below 7.2 ppm, add HTH® Spa pH-Up(Increaser) directly to the filter skimmer with the spa circulation system running. Refer to the on-pack chart for the correct dosage. After the spa circulation system has been running for 30 minutes, re-test pH and add more pH-Up(Increaser) if necessary. Test and balance your spa water twice a week to maintain pH levels between 7.2 and 7.8 ppm.
