Description
- Includes 1 Mineral Cartridge and 3 Bromine Cartridges
- For use with either Serene Floating System or Serene Inline Systems
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 double-teaming bacteria 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.
