FROG Serene Floating System
(Formerly Spa Frog)

Clean, clear hot tub water with less work and less guesswork.

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 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.

Complete starter system includes: One reusable floating holder, one FROG Serene Mineral Cartridge and one FROG Serene Bromine Cartridge, Jump Start Shock & Test Strips.

How FROG Serene Works

The mineral and bromine cartridges work together inside the reusable floating holder to provide continuous hot tub water care.
