How Does the FROG Serene In-Line System work?
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.
How does FROG Serene compare to other bromine floaters or using chlorine?

It contains FROG minerals that destroy bacteria so you need up to 50% less bromine. Plus with the In-Line System everything is tucked away but with easy access when you need it.
How long do the mineral and bromine cartridges last?
The mineral cartridge lasts four months or whenever the hot tub is drained and refilled. The bromine cartridge lasts 2-4 weeks.
