Spa 86133 Ph Up, Crystal, 2 Lb

HTH Spa pH Increaser is a crystal formula designed to balance pH levels in spa and hot tub water. Maintaining proper pH balance is essential for water clarity, comfort, and the effectiveness of your sanitizer. When pH falls below the optimal range, water quality suffers and bathers experience skin and eye irritation.

HTH Spa pH Increaser works with all spa types, including those using bromine, chlorine, or biguanide sanitizers. By raising pH to the recommended 7.2–7.8 ppm range, you help ensure your sanitizer performs effectively and protect spa surfaces and equipment from corrosion. Regular use keeps your spa water clear and inviting.
