Zodiac Nature2 G35 Mineral Cartridge 35000 Gallon W28135

The Nature2 G35 is the genuine Zodiac replacement mineral cartridge for Nature2 Professional G and Pro G Plus in-ground vessels. 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.

🚩 PRO TIP: 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.
