Leisure Time Spa Up pH Increaser for Hot Tubs 2 lbs. (Part # 22339 / 22339A) is a granular pH and alkalinity-boosting chemical specifically formulated for hot tubs and spas. Its fast-dissolving sodium bicarbonate formula gently raises low pH and total alkalinity levels to the ideal 7.2–7.8 range, helping prevent corrosion, scale formation, eye irritation, and poor sanitizer performance. Compatible with chlorine, bromine, ozone and biguanide sanitizers, this pH increaser supports balanced water chemistry, boosts sanitizer effectiveness, and makes routine spa maintenance easier and more reliable. Designed as a direct replacement for Oreq Clear Spa CSSA002 for equivalent water-balancing performance.
