Elevate your spa experience with the FROG Serene Mineral Replacement Cartridge

This cartridge is sized for spas up to 600 gallons, delivering consistent mineral-focused sanitation that aims to keep water comfortable and inviting with less hands-on maintenance.

In everyday use, minerals work to curb organic contaminants and soften water, contributing to a more pleasant soak.

The goal is a clean, clear look and a silky-smooth touch that enhances the natural enjoyment of your spa.
