FROG Serene Refill Kit With Three 150g Bromine Cartridges and One Mineral Cartridge. This kit is designed for the Spa Frog @SereneFloating System.
- (1) Mineral Cartridge
- (3) 150 Gram Bromine Cartridges (each lasts between 2 - 4 weeks)
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.
