Hihitomorrow Mineral Cartridge Replacement for Zodiac Nature2 A30 W28165 — 2-Hole Above-Ground Fit, Treats 5–30K gal

The Hihitomorrow W28165 is a two-hole mineral cartridge designed to replace Nature2 A30 cartridges in most above‑ground A vessels, treating pools from 5,000 to 30,000 gallons.

This replacement cartridge fits Nature2 above‑ground A vessels (except Nature2 Limited) and is built to restore the mineral sanitizing function of Zodiac Nature2 A30 systems. It uses mineral media to support clearer, softer pool water with less reliance on heavy chlorine dosing, while matching common plumbing and housing designs for a straightforward swap.

Will this cartridge fit my Nature2 A30 housing?

The W28165 is made specifically for Nature2 A30 above‑ground A vessels that accept two‑hole cartridges. It will not fit Nature2 Limited models and differs from three‑hole A30 variants, so verify the hole pattern on your old cartridge before ordering.

• Fits Nature2 above‑ground A vessels (non‑Limited) using A30 cartridges
• Two square mounting holes on the cartridge bottom — confirm your original matches
• Compatible with standard pool plumbing and housings for easy installation

How does this mineral cartridge help my pool water quality?

The cartridge contains mineral media formulated to support water clarity and reduce the need for large amounts of chlorine. Using mineral sanitizers can result in softer water feel and lower occurrences of common pool odors, while working alongside your regular sanitizer rather than replacing routine maintenance.

• Mineral media helps limit heavy chlorine dosing when used as directed
• Can contribute to clearer water and a smoother swimmer experience
• Works in combination with existing pool chemicals and feeders

How do I install and maintain the W28165 replacement cartridge?

Installation is simple and designed for most standard above‑ground pool housings. Shut off valves between the cartridge and pool, remove the housing cap, discard the old cartridge, and set the W28165 into place; then reassemble and reopen the valves.

• Turn off valves to prevent pool draining before replacing the cartridge
• Remove housing cap, take out old cartridge, and insert the new W28165
• Replace cartridge every six months for continual performance

Will the cartridge harm pool surfaces or equipment?

The W28165 is manufactured from materials intended to be compatible with standard pool systems and accessories. It is designed not to stain surfaces or corrode equipment when used according to manufacturer guidance and standard pool chemistry practices.

• Constructed from pool-safe materials and mineral particles
• Compatible with most maintenance products and circulating systems
• Does not require alterations to existing plumbing in most setups

Who is this cartridge for? Swimmers and pool owners who use Zodiac Nature2 A30 above‑ground A vessels and want an OEM‑style mineral replacement will benefit from the Hihitomorrow W28165. It’s ideal for medium to large above‑ground pools (5,000–30,000 gallons) where users prefer to reduce heavy chlorine reliance and maintain comfortable water with routine cartridge changes every six months. Check the two‑hole mounting pattern before purchasing to ensure a correct fit.
