PristineCheck

PristineCheck is a water prep that gets the pool or spa ready for the introduction of PristineBlue. It takes excess calcium from the water and deposits it into the filter. PristineCheck is applied in pools when using PristineBlue for the first time and every year at spring opening. In spas, it should be used whenever the spa is refilled . If your source water is high in calcium, we recommend an application of PristineCheck whenever you add make-up water to the pool.
