Transform your spa experience with the FROG Serene Bromine Floating System – the easiest way to maintain crystal-clear, sanitized hot tub water without the hassle of daily testing and measuring. This innovative floating system uses pre-filled bromine cartridges that work continuously to keep your spa water clean, fresh, and ready to enjoy.

Unlike traditional bromine or chlorine maintenance, the FROG Serene system floats in your hot tub and dispenses the perfect amount of sanitizer automatically. You'll enjoy up to 50% less bromine use compared to standard methods, which means less chemical odor, softer water on your skin, and fewer trips to adjust your water chemistry.

How Does the FROG Serene System Work?

The FROG Serene Floating System uses a unique two-part approach to hot tub sanitation. The floating dispenser holds a pre-filled bromine cartridge and a mineral cartridge. As water flows through the system, it releases a controlled amount of bromine sanitizer along with FROG minerals that help condition the water.

This combination means you use less bromine while achieving better results. The minerals help destroy bacteria and create a reservoir of sanitizer, so your water stays cleaner longer between cartridge changes.
