Pre Treatment:
Before initially using Brominating Tablets in your spa or hot tub you will need to add 1/2 oz. of sodium bromide for each 100 gallons of water. The same treatment should be followed each time you drain and refill your spa or hot tub with fresh water.
Treatment:
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 tablet feeder or brominator to obtain an active bromine residual of at least 2 ppm at all times. Spa water has a tendency to foam and cloud; this is directly proportioned to the amount of spa use. Cloudiness is due to the accumulation of body fats, oils, and other 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, draining, clearing and refilling the spa is recommended.
