•BETTER THAN CHLORINE FOR SPAS: Bromine for hot tub performs more effectively than chlorine tablets in hot tubs because bromine stays active in a wider pH range (7.0–8.4) and its byproducts (bromamines) still retain disinfecting power. This ensures consistently clean water without the harshness or inefficiency often found with hot tub chlorine.
