Spa Frog Floating System

Frog Serene Floating System uses pre-filled mineral and bromine cartridges that snap into a reusable floating holder and works in any spa. The Spa Frog Floating System transforms your spa into the environment for soothing relaxation with up to 50% – 80% less bromine than standard bromine spas. Cartridges are easily adjusted to meet the sanitizing 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.
