What customers say
Customers overwhelmingly praise the PoolRx+ Blue Mineral Unit as a highly effective solution for persistent algae, especially in pools up to 20,000 gallons. The core theme is superior water quality and simplified maintenance. Users report crystal clear water, often describing it as softer and sparklier than chemically treated pools. A major benefit is significantly reducing reliance on harsh chlorine. The convenience of dropping the unit in and having it work for months is highly valued. While the initial cost is higher than standard chemicals, the consensus is that the superior performance and reduced long-term chemical expenses justify the investment. Optimal results require maintaining basic water chemistry balance.
Know before you buy
The unit releases a proprietary blend of copper, silver, and zinc minerals that actively kill and prevent algae. Because these minerals handle the algae, your chlorine can focus entirely on sanitizing the water, allowing you to maintain lower, more efficient chlorine levels.
No, the minerals in the PoolRx+ unit are chelated, which means they are chemically treated to remain dissolved in the water. This prevents them from dropping out of solution and causing the staining or scaling often associated with mineral treatments.
No, the PoolRx+ Blue Mineral Unit is not compatible with saltwater pools. It is designed specifically for traditional chlorine-based pools within the 7,500 to 20,000-gallon range.
The unit is designed to last for up to six months. After this period, the mineral core will be depleted and you will need to replace the entire unit to maintain effective algae control.
Yes, you must continue to monitor and balance your pool's pH, alkalinity, and calcium hardness. The PoolRx+ unit works best when your pool water is maintained within the standard pH range of 7.2 to 7.8.
