sixcow Replacement Mineral Cartridge for Nature2 G25 Pools up to 25,000 Gal — W28125 Direct OEM Swap, 6-Month Service

sixcow replacement W28125 mineral cartridge restores Nature2 G25 systems to produce clearer, fresher pool water for pools up to 25,000 gallons.

This aftermarket cartridge is engineered to fit "G" style Nature2 mineral housings (Professional G, Pro G Plus, and compatible G25 vessels) and delivers a convenient mineral-based sanitation boost without altering your existing equipment. Designed as a direct OEM-equivalent swap for part numbers W28125, N2CG25, and W26725, the cartridge uses a blend of mineral media inside a durable PVC shell to release ions and support cleaner swimming water while reducing reliance on traditional chemical dosing.

How does this cartridge help reduce pool maintenance?

The cartridge steadily disperses mineral ions into circulating water, which can complement your sanitizer and slow nuisance algae growth. That steady release means fewer shock treatments and easier weekly upkeep when used as part of a balanced pool care routine.

• Continuous ion delivery for consistent water conditioning
• Can lower the amount of chlorine or other oxidizers you need
• Designed for up to six months of service under normal operating conditions

Will it fit my existing Nature2 Professional G or Pro G Plus system?

This replacement matches the size and connection style of G25 mineral cartridges and is intended as a drop-in alternative for the referenced Nature2 models. Verify your vessel is the G-style housing and accepts cartridges labeled for G25 capacity to ensure a correct fit.

• Compatible with Professional G and Pro G Plus G25 vessels
• Direct replacement for OEM numbers W28125, N2CG25, W26725
• Ideal for systems serving pools up to 25,000 gallons

How do I install and maintain the cartridge?

Installation is straightforward and requires no special tools: turn off the pump, open the mineral housing, remove the old cartridge, and insert the new one following the flow direction. Routine checks and replacing the cartridge every six months (or sooner if recommended by water conditions) keep the system operating as intended.

• Turn off pump and relieve system pressure before servicing
• Replace cartridge approximately every 6 months under normal use
• Inspect housing O-rings and clean the vessel when changing cartridges

What materials and quality controls are used?

The cartridge is built with corrosion-resistant PVC housing and mineral media selected to provide stable performance in pool environments. Manufacturing and testing aim to meet or exceed OEM standards so the unit works reliably without harming pool equipment or surfaces.

• Durable, impact-resistant PVC outer shell
• Mineral media formulated to release silver and copper ions safely
• Manufactured and tested to meet common OEM specifications
