FreshWater Concentrated Chlorinating Granules
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Re-entry into treated spas/hot tubs is prohibited above levels of 5 parts per million (ppm) free residual chlorine. Read all Precautionary Statements before use. Use only a clean, dry scoop to measure this product. Do not use the scoop for any other purpose.
FOR REGULAR DOSAGE
1. Chlorinate: Add 1/2 oz. of this product per 500 gallons of water to the water prior to entering the spa. Wait 5 minutes and then check the chlorine residual. The residual chlorine must read between 2 and 3 ppm. If it does not, additional dosages of material should be added until it does. Once the chlorine residual is established in the 2 to 3 ppm range, the spa or hot tub may be entered.
2. Maintain: This product should be added daily or as necessary to maintain a 2 to 3 ppm residual chlorine reading. Frequent checks should be made of residual chlorine using a reliable test kit. This product should be broadcast over the surface of the water and allowed at least 5 minutes mix time before testing. Note: Heavy bather usage or the use of oils or lotion may increase the chlorine demand of the spa or hot tub resulting in the need for more frequent checks of chlorine residual.
3. Check pH: The pH should be monitored with a reliable test kit and maintained in the 7.2 to 7.8 range for clean, sparkling water. The pH can be decreased by adding a suitable agent such as sodium bisulphate or increased by adding a suitable agent such as sodium bicarbonate.
4. Superchlorization: It is good practice to superchlorinate every 2 to 4 weeks to control odors and algae. To superchlorinate add 1 oz. of this product for every 500 gallons of water. Resume program when chlorine residual reads 2 to 3 ppm.
