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.

 

The alternative way to sanitize

 

Hot tub owners shouldn't have to be weekend chemists. Frog Serene Floating System created a fresh approach to clean water using proprietary. Fresh Mineral Water Technology. You'll find it in all of FROG products - and it offers these four advantages:

 

Softer - Minerals condition the water

Cleaner - Because it kills bacteria two ways - with minerals and a low level of bromine or chlorine

Clearer - Water that shines, minerals help keep the pH balanced

Easier Maintenance - Cartridges are pre-filled for no mess, no guess, no stress!
