Pristine Blue Pristine Check Pool and Spa Prep

The first step in the Pristine Blue system is Pristine Check. Pristine Check rids the pool or spa water of excess calcium that may cause scaling and etching, it then deposits it into the filter to allow you to wash it away.

Dosage: 2 oz per 1,000 gallons of water. 10 milliliters per 100 gallons of water.
