Nature²:
Naturally Clear

For some people bromine and biguanide is not a perfect match in the spa as it adds processed chemicals into the spa. Nature² takes care of this with their sanitizing system that reduces the chemical usage to a fraction of the others. This is accomplished with Nature2's system based on a mineral sanitizer cartridge that works naturally to clean the water. By working naturally Nature2 can keep the water clear and clean while reducing chlorine that some people may be allergic to and reducing the need for time balancing maintaining chemical levels.

A Nature2 system in your spa means you don't have any artificial chemicals in the water to keep it clean. With Nature2 you can run a spa completely bromine and biguanide free for softer and more natural feeling water. All that is needed is to add a new cartridge once every four months and perform regular maintenance such as testing the balance and shocking once a week with a non-chlorine shock.
