Free Shipping $100+ | Genuine Spa Brand Products

  • SpaGuard® Brominating Tablets use an organic brominating compound (BCDMH) compressed into 1-inch tablets, designed to slowly dissolve and provide continuous spa sanitation.

  • These tablets are intended for use in a brominator or floating dispenser and are especially well-suited for spas with heavy bather loads or commercial-style usage. 

  • Because the tablets are acidic, they may lower spa pH levels; users are advised to monitor and adjust pH and total alkalinity frequently. 

  • Available in two size variants — 1.5 lb and 4.5 lb — allowing you to select the size appropriate for your spa volume or usage frequency. 

  • Designed to support effective bromine residuals in spas (typically 2–4 ppm for residential, 4–6 ppm for commercial) when used with correct feeder settings.
