Nature2 W28165 A30 Above-Ground Replacement Cartridge
Part Number: W28165
Description
A mineral cartridge designed for the Nature2 A vessel system, this replacement unit helps sanitize above-ground pools (5,000 to 30,000 gallons) using patented mineral technology to control bacteria and algae and reduce chemical usage.
Compatibility & Fitment
- Fits above-ground pool systems that use the Nature2 A or Pro A Plus vessel (excluding the “Limited” version).
- Use when the current cartridge is expired, showing low performance, or you’re maintaining optimal water clarity and sanitizer reduction.
- Replacement unit for systems specifying part number W28165.
Features & Specifications
- Pool size range: Suitable for sizes from approximately 5,000 to 30,000 gallons.
- Technology: Uses safe, elemental minerals (such as silver and copper) to assist with bacteria/algae control, reducing chlorine demand by up to approximately 50%.
- Maintenance interval: Designed for up to six months of service under typical conditions—heavy bather loads or high temperatures may shorten this interval.
Installation Notes
Shut off the pool pump and relieve circulation pressure if necessary. Open the Nature2 A vessel, remove the old cartridge, clean the interior, then install the new W28165 cartridge per orientation. Close the system, restore pump operation and maintain proper chlorine residual (lower than without the mineral cartridge) and schedule regular water chemistry checks.
Maintenance Tip
Inspect the cartridge every service interval. Replace it if you observe tarnished housing, reduced sanitizer effect, increased chlorine demand or developing algae. Maintaining the cartridge and correct water chemistry ensures optimal performance and extended pool clarity.
