Spa Frog

The Spa Frog System is built into many American made hot tubs. It comprises pre-filled mineral and bromine cartridges that slot into a compartment accessed from the top of the tub.

The Spa Frog mineral cartridge enables hot tubs sanitised with Spa Frog to use 50% - 80% less bromine than hot tubs treated with bromine alone; so there is less chemical use, less chance of skin irritation and less potential for a 'chemical smell'.

The cartridges can either be placed in a re-usable floating holder, or placed into a specially constructed in-line chamber built into the side of many spas.

If you have a Spa Frog in-line system built into your spa you simply open the cap on the side of your tub, pull up the holder and snap in one blue mineral cartridge and one yellow bromine cartridge. The mineral cartridge will last approximately 3 months and the bromine cartridge 2-4 weeks.

Pre-filled cartridges for no-mess water care

Kills bacteria with up to 50% less bromine.
