Its silver and copper mineral media destroy bacteria and control algae for a full season, so the pool stays sanitized with a chlorine residual as low as 0.5 ppm — noticeably less chlorine odor, less irritation, and softer-feeling water. Drop it into the vessel, set the month indicator ring, and the cartridge works for six months.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e🚩 PRO TIP:\u003c\/strong\u003e Always start a new cartridge in clean, balanced water and super-chlorinate at startup to activate the mineral media. Mark the install month on the indicator ring — a cartridge should never run longer than six continuous months.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES \u0026amp; SPECIFICATIONS:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Zodiac Cartridge:\u003c\/strong\u003e Factory replacement for Nature2 Professional G and Pro G Plus vessels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral Sanitizing:\u003c\/strong\u003e Silver and copper media destroy bacteria and control algae\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Chlorine:\u003c\/strong\u003e Sanitizes with a chlorine residual as low as 0.5 ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e Pools up to 35,000 gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge Life:\u003c\/strong\u003e 6 months or one season, whichever is shorter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Vessel:\u003c\/strong\u003e Nature2 Professional G vessel W25904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Zodiac\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e W28135\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pool \u0026amp; Spa Sanitizers\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFREQUENTLY ASKED QUESTIONS:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Which vessel does the G35 fit?\u003c\/strong\u003e\u003cbr\u003eA: The G35 fits Zodiac Nature2 Professional G and Pro G Plus in-ground vessels, including vessel model W25904, serving pools up to 35,000 gallons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: How long does one cartridge last?\u003c\/strong\u003e\u003cbr\u003eA: One cartridge lasts six months or one pool season, whichever is shorter.
