PoolRX+ Blue/White Booster (with silver) (7.5K-20K gal) Treats 7.5K – 20K gallons Eliminates All Algae Reduces Chemical Demand Simplifies Pool Care NSF/ANSI 50 Certified The PoolRx+ booster contains the additional granular material needed to replace minerals that are lost through backwash, splash out, and algae kill. PoolRx+ booster can also be used for larger pools that need additional minerals when initially installing a PoolRx+ pool unit. The booster must be used with your previously purchased PoolRx+ pool unit. The granular does not need to go back into the PoolRx+ pool unit; it just needs to dissolve back into the pool water. The granular generally needs to be replaced every 4-6 months, depending on your swim conditions.
