Nature 2 G Cartridge (up to 25K Gallons) W28125
The Nature2 W28125 Professional G25 replacement mineral cartridge works with the Nature2 Professional G or Pro G Plus sanitizer vessel (vessel not included), and is designed for in-ground pools up to 25,000 gallons. The G25 sanitizer cartridge delivers improved water clarity, and clean, safe water without the harsh effects of traditional chlorine-based treatments. Each W28125 G25 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. The W28125 has an alternative part number of W26725. Please do not use Nature2 with copper-based algaecides, bromine or bromide chemcials, or Biguanides.
