Product Description

The Pool FROG® Replacement Mineral Reservoir is a genuine prefilled cartridge designed for use with Pool FROG® Model 5400 and XL PRO Cyclers.
It uses FROG® mineral technology to create Fresh Mineral Water®, which keeps pool water crystal-clear, soft, and comfortable while using up to 50% less chlorine.
The minerals work continuously with a small, steady chlorine level to destroy bacteria and prevent algae growth for a cleaner, easier-to-maintain pool.
This cartridge is simple to use—just wet, insert, and replace every six months or one full pool season.
Designed for in-ground and above-ground pools using compatible Pool FROG® Cyclers.
The mineral formula provides silky-smooth water that’s gentler on skin, eyes, and swimsuits.
It’s a quick, no-mess alternative to traditional chlorine dosing, ensuring consistent sanitization without daily handling or measuring.
