Same quality as Aquabrome®, Leisure Time®, Bioguard®, and Guardex®. These 1/2 oz. compressed bromine tablets are a gentler alternative to chlorine for your spa or hot tub. Bromine is slow dissolving, more stable sanitizer than chlorine when used in warm water conditions, so the tablets last much longer. Add tablets to your spa skimmer or floater until you reach 2 to 4 ppm (parts per million) of bromine residual in your spa or hot tub. Since Bromine Tablets will not give an immediate bromine reading in new fill spa or hot tub water, Go Brom is recommended every time you re-fill for a immediate Bromine reading. You can add a 1lb. jar of Go Brom in the drop down menu below.
