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.
