How PoolRx+ Works
PoolRx+ uses a proprietary mineral formulation contained inside a specially treated alloy cylinder. Once placed in the pool's circulation system, the minerals dissolve and distribute throughout the swimming pool water. These minerals work together to control algae and allow chlorine to work more efficiently.
As water continues circulating through the PoolRx+ cylinder, the mineral protection is replenished, helping maintain effective algae control for up to six months under normal operating conditions.
Installation Instructions
- Verify that the swimming pool contains between 7,500 and 20,000 gallons of water.
- Clean or backwash the pool filter before installing the unit.
- Remove debris from the skimmer and pump baskets.
- Check water chemistry and maintain a pH between 7.2 and 7.8.
- Place the PoolRx+ unit directly into the skimmer or pump basket with adequate water circulation.
- Allow the pump to operate for at least 3–4 hours after installation to circulate the minerals.
- Leave the PoolRx+ cylinder in the circulation system after the minerals have dissolved.
- Maintain the recommended sanitizer level and water balance according to the manufacturer's directions and applicable regulations.
