PristineCheck® is a water prep that gets your pool, spa or swim spa ready for the introduction of PristineBlue®. It’s essential to backwash or clean the filter after the use of PristineCheck®. If your source water is high in calcium, we recommend an application of PristineCheck® whenever you add makeup water to the pool, spa or swim spa.
Application rate: For pools add 2 ounces per 1,000 gallons. Filter for 24 hours; then backwash the filter or remove and clean the cartridge.
Available Sizes: 8 oz., 32 fl oz, 64 fl oz
