Natural Chemistry's Spa Bromine Tabs provide an active bromine residual to sanitize spa water.
Directions:
Spas: Before initially using this product in your spa or hot tub, you will need to add 1/2 oz. of sodium bromide for every 100 gallons of water. The same treatment must be followed each time you drain and refill your spa or hot tub with fresh water. Introduce 3 tablets per 300 gallons of spa water with the use of a floating tablet feeder or automatic brominator installed on the spa equipment. Adjust the tablet feeder or brominator to obtain an active bromine residual of at least 2 ppm. Maintain spa by adding 3 tablets per 300 gallons every 5-7 days or as needed to maintain an active bromine residual of 2 ppm at all times. Spa water tends to foam and cloud. This is directly proportional to the amount of spa use. Cloudiness is due to the accumulation of body fats, oils, and contaminants too small for the filtration equipment to remove, and is linked to rapid escalation of total dissolved solids in the water. To a great extent, defoamers, clarifiers, as well as shock treatments, demineralizers, or sequestering agents can be used to clear the water. When water clarification cannot be achieved, drain, clean, and refill the spa.
