Why You'll Love It

This pre-filled mineral cartridge pairs with your bromine cartridge (sold separately) to create the perfect water care duo.

Perfect For

Hot tub owners who want to spend less time maintaining their spa and more time enjoying it. FROG mineral technology works harmoniously with bromine to create a more natural, less chemical-dependent sanitizing system.

Installation

Installation is a snap – simply replace your old cartridge with this new one when your spa needs a refill or after four months of use. No measuring, no mess, no stress.
