Start-Up:
Add 1/2 oz. of this product per 500 gallons prior to entering spa.
Wait 5 minutes then check chlorine residual.
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.

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.
This product should be broadcast over the surface of the water and allowed at least 5 minutes mix time before testing.

Super-chlorination:
Super-chlorinate every 2 to 4 weeks.
To super-chlorinate, add 1 oz. of this product for each 500 gallons.
Thoroughly clean spa, vacuum and cycle through filter.
Resume program when chlorine residual reads 2 to 3 ppm.

Tips:
Shocking the spa after each use will destroy organic bather waste.
