SeaKlear Spa Brominating Tablets are an easy and effective way to add critical bromine to your spa or hot tub, protecting it from bacteria and other organic threats. Bromine not only eliminates the foul chemical odors of chlorine, but is less irritating to skin and eyes. Simply add these slow-dissolving tablets to your floater or feeder for a continuous level of bromine circulating throughout your pool. These tablets also continue to remain effective over a much broader pH range than chlorine. Best of all, Spa Brominating Tablets are made to the exacting standards SeaKlear demands of all its products, allowing you to buy with confidence.
