Lower your bromine use up to 50%* with FROG minerals
The FROG Serene 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.

Hot tubs 150 to 600 are perfect for FROG Serene.
