How it works
The SPA FROG Fresh Mineral Water In-Line System is part of the hot tub's plumbing, with an easily distinguishable and convenient cap for top loading of the mineral and bromine cartridges. A simple twist and the cartridge basket is removed from the hot tub for quick and easy cartridge replacement. The entire process takes less than a minute. The minerals last a full four months set wide open, while the bromine usually lasts around three weeks with adjustable settings to meet each hot tub's needs.
