The PoolRx Sundance Spa Unit is a continuously effective algae eliminator that is made up of a proprietary blend of minerals. Using a specially treated alloy cylinder, the minerals in the unit dissolve out of the cylinder that forms a steady residual throughout the spa for up to 6 months. This product will eliminate algae so that low levels of chlorine can be more effective in the water. The minerals in the spa unit are replenished every time they return through the cylinder so that the chlorine in the water can last as long as possible.
