FROG Serene Floating Sanitizing System creates Fresh Mineral Water in your hot tub by killing bacteria two ways - with minerals and a low level of bromine. FROG Serene keeps your hot tub clean while eliminating the work and guesswork. Instead of spooning in chlorine daily, you simply replace a pre-filled bromine cartridge about once a month. With up to 50% less bromine*, you'll experience softer feeling water that's easier on skin, swimsuits and spa surfaces. Cartridges are easily adjusted to meet the sanitizing needs of hot tubs up to 600 gallons. The system comes with a start-up shock called FROG Jump Start and an introductory bottle of FROG Test Strips. Keep the green holder while replacing the blue mineral cartridge every 4 months (or when you drain and refill your hot tub) and the yellow bromine cartridge every 2-4 weeks depending on use. *Compared to the minimum ANSI recommended bromine level of 2.0 ppm for a hot tub.

Bromine unstable
Bromine reads zero. I had water tested ph, alkalinity and hardness perfect. After following directions and turning opening up to 6 for 260 gallons still no read.

Clogs and chemicals won't come out
It's easy to put canisters in holders but difficult to set canisters on correct setting and water mixes with chemical and clogs the holes. Had to buy extra bromine to keep adding to my hottub. Will go back to chlorine frog on next fill.
