DIRECTIONS FOR USE

1. Chlorinate: With jets running, add .25 oz. (one, ONEshock� dissolving packet) of this product per 250 gallons of water. Wait 5 minutes, then check chlorine residual. Residual chlorine must read between 2 to 3 ppm.

2. Maintain: This product should be added daily or as necessary to maintain 2 to 3 ppm residual chlorine. Frequent checks should be made of residual chlorine using a reliable test kit. Allow at least 5 minutes mix time before sampling. 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: pH should be monitored with a reliable test kit and maintained at 7.2 to 7.8 range for clean, sparkling water. 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. SUPER-CHLORINATION: It is good practice to super-chlorinate each 2 to 4 weeks. To super-chlorinate, add 1/2 oz. (two, ONEshock� dissolving packets) of ONEshock� for each 250 gallons of water. Thoroughly clean spa, vacuum and cycle through filter. Resume program when chlorine residual reads 2 to 3 ppm.
