Sodium Bromide establishes an immediate bromide reserve in your spa.
No more waiting after re-filling your spa! Add to new fill water for an instant bromine residual. Just add bromine tablets or shock immediately after using to activate. Reduces the amount of bromine and time it takes to reach the ideal bromine reading of 1-3 ppm.
Sodium Bromide is NOT a disinfectant. It is used to establish a reserve of bromide in spa or hot tub water. It is necessary to use a sanitizer to disinfect the water.Dosage: 0.5 oz per 100 gallons
