Nature2 W28145 G45 Replacement Mineral Cartridge for Professional G
The Nature2 W28145 Professional G45 replacement mineral cartridge works with the Professional G sanitizer vessel (vessel not included), and is designed for in-ground pools up to 45,000 gallons. The Professional G sanitizer delivers improved water clarity, and clean, safe water without the harsh effects of traditional chlorine-based treatments. Each W28145 G45 cartridge lasts for 6 months, and has a flow rate of 10-18 GPM (internal bypass). The cartridge does not contain harsh chemcial pool additives, and allows you to reduce the chlorine level in your pool to 0.5 ppm, which in turn helps to keep your pool pH balanced. Further, Zodiac's Nature2 mineral sanitizing products for the pool and spa dramatically reduce the need for heavy doses of chlorine and provide an eco-friendly choice for pool and spa maintenance.
