SpaPure Brominating Tabs are a concentrated, slow-dissolving bromine sanitizer built for hot tubs. The active ingredient is BCDMH (bromochloro-5,5-dimethylhydantoin) at 98% — a tablet form of bromine that dissolves slowly and evenly and drops right into most spa floaters and feeders for hands-off, continuous sanitation. Bromine is the sanitizer many hot tub owners prefer, and for good reason. It gives you the effectiveness of chlorine without the chlorine odor, it's gentler on skin and eyes, and it stays effective in the hot, agitated water of a spa across a wider pH range than chlorine does. Where chlorine can feel harsh in a small, heated tub, bromine tends to feel milder. Because the tabs release slowly from a feeder, they hold a steady sanitizer level between soaks instead of the peaks and dips you get from dosing by hand — set the feeder and the spa stays continuously protected. Pro Tip: Bromine tabs need a head start. On a fresh fill, add sodium bromide first to seed the water with a bromide reserve — the "bromide bank" — before you rely on the tabs. Without that bank, a brand-new fill takes much longer to reach a protective bromine level. Establish the bank once at startup and the tabs keep it topped up from there. Brand SpaPure®
