Pristine Extra 4lb

PristineExtra® is a 99% sodium di-chlor shock that is used in the start up of PristineBlue®. It dissipates rapidly, therefore rendering the water back to a non-chlorine status. PristineExtra® may be used for troubleshooting. Application rate: For pools add 1 pound per 10,000 gallons at start up. For spas add 5 milliliters (or 1 teaspoon) per 100 gallons at start up.
