Pro Series Boric Acid is a water enhancer that buffers and helps keep pool water balanced, providing soft and clear swimming pool water. Pro Series Boric Acid helps brominating, chlorinating or biguanide programs to work more efficiently. Designed for once-a-year use and topping off as needed, simply add 15 pounds of ProSeries Boric Acid into 10,000 gallons of water. Test borate levels twice a year (or more often if water is lost) and maintain a borate residual between 30 to 35 ppm to see amazing benefits all season.
