Our FROG Serene System is so popular, some spa brands have built it directly into their spas. It makes hot tub care even easier, and your hot tub experience even more luxurious. With FROG Serene, there's no measuring out the right amount or constantly adding chemicals. You simply replace your FROG Serene cartridges when used up and enjoy weeks of Fresh Mineral Water®. Can be used with both the chlorine and bromine cartridge.
