Item #102066

PoolRx™ helps eliminate algae and reduce the amount of chemicals used to sanitize the pool. Place it in your skimmer or pump basket, and it instantly becomes effective. The specially treated alloy cylinder is packed with a blend of minerals that rejuvenate every time they pass back through the cylinder.

PoolRx™ is also ideal for salt water pools by reducing the salt chlorine production needed to keep your salt pool algae free. Less salt chlorine production extends the life of the salt cell and reduces the amount of acid needed to balance the pH.

The cylinder last up to 6 months, at which time you may need to add a booster pack according to the gallons of pool water.

The granular does not need to go back into the PoolRx+ pool unit; it just needs to dissolve back into the pool water.
