Pool Rx Plus Booster Black 20-30K Gallons 4PK

PoolRx+ contains a proprietary blend of minerals that continuously and effectively eliminate algae. The specially treated alloy cylinder is packed with PoolRx+ granular formulation. These minerals immediately dissolve out of the cylinder and form a stable residual throughout the pool water for up to 6 months. The minerals eliminate the algae while freeing up low levels of chlorine to be more active and productive in the water. During the filtration process, the minerals are rejuvenated every time they return and pass through the cylinder.
