Specifically formulated for spas and hot tubs, this concentrated dichlor granular chlorine effectively sanitizes and shocks hot water to help keep it clean and clear.

Dosage

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 to 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, spa or hot tub may entered.

Maintain

This product should be added daily or as needed to maintain a 2 to 3 ppm residual chlorine reading. Heavy bather usage or the use of oils or lotions may increase the chlorine demand of the spa or hot tub resulting in the need for more frequent check of chlorine residual. 

Check pH

The pH should be monitored with a reliable test kit and maintained in the 7.2 - 7.8 range for clean, sparkling water. The pH can be reduced or raised by adding a pH reduced or increaser.

Superchlorination

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 between 2 to 3 ppm.
