The Nature2® Pro G35 Replacement Cartridge is the ultimate low-chlorine alternative for sanitizing inground pools up to 35,000 gallons. Its revolutionary combination of Nature2® mineral technology and an automatic chlorine feeder allows you to enjoy your pool more and less time maintaining it. The cartridge's two-post design fits two-post professional vessels for pools from 25,000 to 35,000 gallons.
