What is PoolRX Algaecide Blue?
PoolRX Algaecide Blue is a mineral-based algae prevention system that uses a slow-release chelated mineral technology to prevent algae growth in swimming pools. Unlike traditional liquid algaecides that require weekly application, PoolRX uses a physical unit placed in your pool's circulation system that continuously releases minerals for 4 to 6 months. This innovative approach provides season-long algae prevention while reducing chlorine consumption and chemical usage.
Key Features of PoolRX Algaecide Blue
- Mineral-based system: Uses chelated minerals for algae prevention
- Slow-release technology: Continuous protection for 4 to 6 months
- Reduces chlorine needs: Cut chlorine usage by up to 50%
- Easy to use: Simply place in skimmer or pump basket
- Long lasting: One unit lasts entire season
- Safe for all surfaces: Compatible with vinyl, fiberglass, plaster, and tile
- Works with all sanitizers: Compatible with chlorine, salt, and mineral systems

How PoolRX Works
PoolRX Algaecide Blue contains chelated minerals that slowly dissolve as water flows through your pool's circulation system. These minerals are distributed throughout the pool, creating an environment that prevents algae growth. The slow-release formula ensures consistent mineral levels for months, eliminating the need for weekly liquid algaecide applications.
