Low Total Alkalinity of your pool water may result in corrosion to metal and plaster components of your pool system, cause staining, etching or distortion. By raising the Total Alkalinity of your pool with TropiClear^® Alkalinity Control, you not only prevent these problems, but also eliminate “pH bounce” by buffering the water against changes in the pH. The Total Alkalinity of pool water should be maintained between 80-120 ppm.
