SpaGuard Total Alkalinity Increaser - 2 lbs
SpaGuard Total Alkalinity Increaser works by raising the total alkalinity in hot tub water. Low total alkalinity leads to problems like corrosive spa water that causes staining, etching, or the distortion of hot tub surfaces. Balanced alkalinity levels in your spa water reduces the occurrence of “pH bounce” by buffering the water against pH changes. Total Alkalinity should ideally be retained in the 125-150 ppm range.
