FROG Serene® Floating System (formerly SPA FROG)
Complete Hot Tub Sanitizing Floater creates Fresh Mineral Water
FROG Serene keeps your hot tub clean while eliminating the work and the guesswork. Instead of spooning in chlorine 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.
