Poolife Back to Blue Shock System

This two-part system destroys the bacteria and algae that has taken over you pool, then makes it easy to vacuum out. Get an all-in-one shock system that chlorinates, shocks, and kills algae to restore water clarity. If any granules settle to the bottom of the pool, use a brush to disperse to assist in helping it dissolve. Once this product has been completely dispersed in the pool water, change valve to recirculate position and add 2 lbs of Poolife Exclusive Pool Care Collection Back to Blue 2 per 15,000 gallons of water through the skimmer. Leave system circulating for 1 hour, then turn off the filter pump and allow water and sediment to settle overnight. The following day, change valve to vacuum position and vacuum the sediment to waste. Return valve to filter position after pool has been vacuumed.
