Frog Serene Mineral Cartridge
Product Overview
A proven choice for spa owners looking to reduce chemical harshness through mineral-based water conditioning.
The FROG Serene Mineral Cartridge (EPA Reg #: 53735-11) utilizes 0.5% Silver Chloride to help maintain water clarity in spas up to 600 gallons. This 2.05 oz cartridge is designed for use with FROG floating or inline systems, working alongside bromine to keep residual levels at a steady 1 ppm. In our experience, this mineral-first approach creates a softer feel on the skin and eyes compared to high-chlorine alternatives.
