Nature2 FusGemini said Zodiac Nature2 Fusion & DuoClear 45 Mineral Replacement Cartridge | Up to 45,000 Gallons | W28002ion/DuoClear 45 Cartridges, 45,000 gallons, Single Unit | W28002

The ultimate mineral purification upgrade designed to deliver incredibly clear, exceptionally soft, and naturally balanced water for large residential pools. The Zodiac Nature2 W28002 replacement cartridge is engineered specifically for use in Nature2 Fusion, Nature2 Fusion Soft, and DuoClear systems. Utilizing proprietary mineral-bed technology, this single-unit drop-in cartridge releases trace amounts of silver and copper into your pool water, actively destroying bacteria and controlling algae growth in high-capacity pools up to 45,000 gallons.

By harnessing the power of natural minerals, the Nature2 system handles a massive portion of the sanitizing heavy lifting, allowing you to drastically reduce your pool’s reliance on harsh traditional chlorine. The result is "bottled-water quality" clarity that feels remarkably silky on the skin, completely eliminating the red eyes, dry hair, faded swimsuits, and overpowering chemical odors associated with heavily chlorinated water.

Features

High-Capacity Output: Specifically calibrated to handle the heavy demands and large water volumes of in-ground pools up to 45,000 gallons, ensuring your expansive backyard oasis remains consistently pure and perfectly balanced.

Powerful Mineral Purification: Contains a highly effective, EPA-registered blend of silver and copper minerals. The silver actively neutralizes harmful bacteria and viruses, while the copper acts as a potent, long-lasting algaecide to keep your water brilliant and clear.

Dramatically Reduces Chlorine Use: Because the active minerals are constantly fighting off contaminants, your pool requires a significantly lower free chlorine residual (as low as 0.5 ppm) to stay perfectly safe. This translates to lower chemical costs and a much healthier swimming environment.

Extended 6-Month Lifespan: Designed for true "set it and forget it" convenience. A single W28002 mineral cartridge is engineered to last for a full six months, easily providing an entire season of premium, hands-free water care without the need for constant monitoring or refilling.

Broad System Compatibility: This versatile cartridge acts as the exact OEM replacement for multiple Zodiac/Jandy systems, sliding perfectly into Nature2 Fusion Inground systems, Nature2 Fusion Soft (saltwater) systems, and legacy DuoClear vessels.

Improves Water Quality & Comfort: By reducing chlorine demand and actively conditioning the water as it flows through the filtration system, the minerals create a noticeably softer, silkier water texture that is gentle on sensitive skin and eyes.
