The PoolRx Yellow Spa Unit - 100-400 - Original (101057) unit contains a proprietary blend of minerals that continuously and effectively eliminate algae. The specially treated alloy cylinder is packed with PoolRx+ mineral formulation. These minerals immediately dissolve out of the cylinder and form a stable residual throughout the spa water. The minerals eliminate the algae while freeing up low levels of chlorine to be more active and productive in the water.
