Nature2 W28155 Replacement Mineral Cartridge
Part Number: W28155
Description
The Nature2 W28155 mineral cartridge is designed for use with Nature2 M-Series (M25) in-ground mineral sanitizing systems for pools sized up to 25,000 gallons. This cartridge utilizes copper and silver minerals to assist in controlling bacteria and algae, reduce chlorine demand, and help provide clearer, softer water.
Compatibility & Fitment
- Designed for pools 5,000 to 25,000 gallons when used with a compatible Nature2 M-Series vessel.
- Direct replacement for previous models labeled “Type M-25”.
- Intended for in-ground installations; not for above-ground systems unless explicitly specified.
Features & Specifications
- Mineral sanitizing cartridge containing copper and silver.
- Typical service life: up to six months (one swimming season) under proper operating conditions.
- Marked “W28155” and fits into the M-Series vessel used in Nature2 systems.
Installation Notes
Before installing, ensure the pool water is balanced (pH, alkalinity, calcium hardness). Turn off pump and isolate filtration system. Remove the old cartridge from the mineral vessel, insert the W28155, secure and re-start circulation. Monitor free chlorine to verify reduced demand—typically about 50% less chlorine is required when mineral system is functioning correctly.
Maintenance Tip
Regularly check the pool water every week for chlorine residual, mineral cartridge condition and general water clarity. Replace the cartridge at the six-month mark or sooner if water clarity or sanitizer levels deteriorate. Using the proper mineral cartridge helps extend the swim season with lower chemical use and improved swimmer comfort.
