PoolRx Extreme Black Chemical Removes Algae For Swimming Pools - (Various Size)

Description

PoolRx™ helps eliminate algae and reduce the number 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 proprietary blend of minerals that rejuvenate every time they pass back through the cylinder. The cylinder lasts up to 6 months, at which time you may need to add a booster pack according to the gallons of pool water. PoolRx™ is also ideal for saltwater 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.
