SPA FROG Floating System uses pre-filled mineral and bromine cartridges that snap into a reusable floating holder and works in any hot tub.

The SPA FROG® Floating System transforms your spa into the perfect environment for soothing relaxation with up to 50% - 80% less bromine than standard bromine spas. Cartridges are easily adjusted to meet the sanitising needs of virtually any size spa. Replace the mineral cartridge every 4 months when you drain and refill your spa. The bromine cartridge will last 2-4 weeks depending on use.

Use with the FROG 4 in 1 test strips for optimal results.
