What customers say
Customers overwhelmingly praise the PoolRx+ unit for its exceptional algae prevention and maintenance simplification.

This product is highly regarded for solving persistent algae issues.
Know before you buy
The unit contains a proprietary blend of minerals—including copper, zinc, and silver—housed in a treated alloy cylinder. As water circulates through the unit, these minerals are released to continuously kill algae and prevent new growth, which also helps your existing chlorine work more efficiently.
No, the PoolRx+ Blue/White unit is not compatible with saltwater pool systems. It is designed specifically for traditional chlorine-based pools.
The mineral cylinder is designed to be effective for up to six months. After that period, you will need to replace the unit to maintain consistent algae prevention.
This specific unit is calibrated for pools between 7,500 and 20,000 gallons. Using it in a pool smaller than 7,500 gallons may result in an over-concentration of minerals, so it is best to choose a model sized appropriately for your specific water volume.
No, it does not replace chlorine. Instead, it acts as a powerful algaecide that enhances the productivity of your chlorine, allowing you to maintain a cleaner pool with less chemical maintenance.
Yes, the product is not pH neutral. You should continue to monitor your pool's chemistry regularly and adjust your pH levels as needed to ensure the water remains balanced and safe for swimming.
