INSTRUCTIONS

Directions for use:


Read entire label and use strictly in accordance with precautionary statements and directions.


Keep pH between 7.2 and 7.6 and never allow it to fall below 7.0. The treatment necessary for your pool or spa will change considerably depending upon those factors that burden the disinfection system.

Some of the factors that will vary the required treatment are water temperature, bather load, exposure to windblown debris, thunder or rain storms and length of filtration cycle. Must wear chemical-resistant gloves while putting tablet in the swimming pool/spas.


Spas:​

Before initially using this product 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 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 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 has a tendency 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 to 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.
