- Before adding ProGuard® Boric Acid, bring a sample of the pool water or fill water to your local professional dealer to have the water tested and balanced to proper levels. Also, backwash or clean filter before adding this product.
- Then add 15 lbs of ProGuard Boric Acid per 10,000 gallons of pool water (1.5 lbs per 1,000 gallons). Slowly add ProGuard Boric Acid into your pool skimmer with the pump and circulation system on.
- Allow pool water to circulate for 4-8 hours after application. Do not pour ProGuard Boric Acid into a skimmer if circulation is not evident in the skimmer. Do not directly combine ProGuard Boric Acid with any other product.
- Test your pool water on a regular basis for pH and sanitizer residual and adjust as necessary. Twice a year, bring a pool water sample to your local professional pool dealer for testing of your ProGuard Borate Acid level and pool water balance.
NOTE: If the water level is significantly reduced or drained and refilled, then water should be retested by your dealer. If your dealer determines that additional ProGuard Borate Acid is required, add amounts indicated by dealer, following instructions above for proper application.
