Raises alkalinity level to protect spa water from sudden changes in pH.
The carbonates in water help stabilize pH. But both the heat and aeration of spas drive out carbon dioxide. Consequently, pH in spas tends to rise. A fluctuating pH can cause problems such as swimmer discomfort, equipment deterioration, water cloudiness and chemical inefficiency.
Control these pH fluctuations by making sure you have the proper total alkalinity level.
