The Spa Frog floating system uses pre-filled mineral and bromine cartridges that snap into a reusable floating holder. This mineral spa system will work in any brand hot tub / spa. The benefit of using a Spa Frog Bromine Mineral system versus any other bromine system is that you use up to 50% less bromine than standard bromine spas. The Bromine cartridge is adjustable to meet the demand of any size spa.
