Save time and money by using pH Balance to keep pH and alkalinity levels stable in your spa water. Add pH Balance to freshly filled spa water after the pH and alkalinity are initially balanced. This will help to prevent pH and alkalinity levels from bouncing around. Not recommended for areas with hard water.
