How does the Onylraep mineral cartridge work with my existing DuoClear or Fusion system?

The cartridge contains natural mineral media that releases trace elements into circulation. Those minerals help moderate organic build-up and work alongside your sanitizer, meaning the system needs less chlorine or other oxidizers to maintain clear water.

• Fits W28000/W28001/W28002 compatible heads and housings.
• Used in Zodiac Duoclear 25/35, Nature2 Vision Pro, Fusion Inground systems.
• Designed for pools up to 45,000 gallons.
• Installs in minutes—no special tools required.

What materials are in the cartridge and are they pool-safe?

The cartridge combines ceramic-like mineral beads with a durable PVC shell. Components are chosen to resist corrosion, impact and aging so they won’t damage pool equipment or leave residue on pool surfaces.

• Ceramic-particle mineral media for steady release.
• Reinforced PVC housing resists wear and pool chemicals.
• Non-staining construction formulated for pool use.
• Manufactured to avoid adverse equipment interactions.

How often should I replace the cartridge and what maintenance is required?

For reliable performance, replace the mineral cartridge about every six months under typical use. Replacing on that cadence keeps the mineral output consistent and helps minimize the amount of supplemental sanitizer you need to add.

• Recommended replacement: ~every 6 months for best results.
• Check compatibility before installation (W28000/W28001/W28002).
• Less frequent chemical adjustments mean lower maintenance time.
• Follow system manufacturer instructions alongside cartridge use.

Will switching to this cartridge reduce my chlorine use and pool odors?

The mineral media helps control organic contaminants, which can reduce reliance on chlorine and lessen common odors. Results depend on factors like bather load, weather, and starting water quality, so continue periodic testing and sanitizer adjustments.

• Supports reduced sanitizer demand when used correctly.
• Helps with clearer water and fewer nuisance smells.
• Not a replacement for routine pool testing and chemical balancing.
• Best used as part of a complete filtration and treatment routine.
