Raises total alkalinity in spa water. Low total alkalinity may cause spa water to be corrosive to metal causing staining, etching or distorting of spa surfaces. Proper alkalinity reduces "pH bounce" by buffering the water against undesirable pH changes. Total alkalinity should be maintained in the range of 125-150 ppm.
