The PoolRx+ 331003 Blue/White Mineral Algaecide 4-Pack provides convenient, long-lasting algae control for swimming pools containing 7,500 to 20,000 gallons of water. Each package contains four individual PoolRx+ Blue/White mineral units, allowing pool owners and service professionals to maintain multiple pools or keep replacement units available for future treatments.

How PoolRx+ Mineral Algaecide Works
Each PoolRx+ unit contains a specially treated alloy cylinder filled with mineral granules. Once installed in the swimming pool circulation system, the granules dissolve into the pool water, distributing algae-controlling minerals throughout the pool.
The minerals help eliminate existing algae and prevent new algae growth. As pool water circulates through the filtration system, the PoolRx+ unit helps maintain the mineral treatment.
PoolRx+ works alongside chlorine sanitation and is not intended to replace the primary pool sanitizer.
Benefits of the PoolRx+ 4-Pack
- Four individual units provide treatment for up to four appropriately sized pools at a time.
- Convenient for professional pool service routes.
- Allows spare units to be kept for future seasonal maintenance.
- Helps control algae in both traditional chlorine and saltwater pools.
- May reduce supplemental algaecide use when operated according to manufacturer directions.
- Provides a convenient mineral-based addition to routine pool maintenance.
Installation Instructions
- Verify that the swimming pool contains between 7,500 and 20,000 gallons of water.
- Test and balance the pool water according to PoolRx manufacturer instructions.
- Clean the pool filter and pump basket before installation.
- Remove one PoolRx+ Blue/White unit from the package.
- Place the unit in the pump basket or skimmer as directed by the manufacturer.
- Operate the circulation system to distribute the mineral formula throughout the pool.
- Continue testing and maintaining appropriate sanitizer levels and balanced water chemistry.
- Replace or supplement the mineral treatment as directed by the product label and pool operating conditions.
Important: Each mineral unit is intended for a pool within the specified gallon range. Do not automatically install all four units into one swimming pool. Use the manufacturer-recommended treatment quantity for the actual pool volume.
PoolRx+ and Saltwater Pools
PoolRx+ can be used with compatible saltwater chlorine generator systems. The mineral treatment helps control algae while the saltwater chlorine generator continues producing chlorine for pool sanitation.
Maintain the sanitizer residual and water chemistry required for the pool. PoolRx+ does not eliminate the need for chlorine or routine pool water testing.
