SpaGuard’s Total Alkalinity Increaser provides spa owners with a simple, effective treatment to combat spa alkalinity that is too low. Which, if left untreated, can cause corrosion damage, weaken your sanitizer’s ability to keep your spa clean, and cause skin and eye irritation. Total Alkalinity Increaser’s formula reverses these effects, as well as stabilizing your spas pH level to prevent pH bounce that can give spa owners headaches. Once applied, you can spend more time enjoying your spa rather than maintaining it.
