SpaGuard® pH Increaser is a quick-dissolving granular formula designed specifically for spas and hot tubs, to raise dangerously low pH levels and improve water comfort and clarity. This product helps protect equipment, plumbing and surfaces from corrosion or damage that can occur when water pH falls too low. The formula is compatible with standard spa sanitizing systems including chlorine, bromine, salt and ozone; when pH is properly balanced your sanitizer works more effectively. Simply add the correct dose while the circulation system is running and retest after. Ideal for use when pH drops below the recommended range (typically 7.2-7.8). Available in 18 oz size, making it convenient for routine maintenance and refills of most standard home spas. Show more
