Solus pH Down Spa pH Decreaser is used to lower the pH in spa water. The water in the spa should be maintained at a pH of 7.2-7.8 and total alkalinity should be maintained at a level of 80-140 ppm (parts per million). Test spa water frequently with a suitable spa water test kit to ensure that the proper pH is maintained. Solus pH Down is compatible with all sanitizers including bromine, chlorine and biguanide.
