FROG® Serene® Floating System

FROG Serene keeps your hot tub clean while eliminating the work and the guesswork. Instead of spooning in bromine daily, you simply replace a pre-filled cartridge about once a month. FROG Serene works by killing bacteria in two ways with sanitizing minerals and a very low level of bromine. The resulting Fresh Mineral Water® has a completely different quality that provides the serene feeling you’re looking for. Spa Frog Serene Floating System uses mineral and bromine cartridges with a reusable floating holder that works in any hot tub. Cartridges are easily adjusted to meet sanitizing needs.
