• Up to 75% LESS CHLORINE with no frustrating "yo-yo" chlorine levels

Introducing the innovation of SmartChlor Technology – the self-regulating chlorine that works together with FROG minerals in the easy to use FROG® @ease® Floating System. Enjoy the benefits of Fresh Mineral Water that’s cleaner, clearer, softer and easier to take care of with the unique properties of SmartChlor Technology that uses up to 75% less chlorine* and greatly reduces hot tub maintenance like shocking.

How It Works

The @ease System combines the proven FROG mineral formula for killing bacteria with SmartChlor Technology that maintains a consistently low chlorine level for weeks. Unlike normal chlorine that is used up when you get in, SmartChlor continues to maintain the same level which is up to 75% less than hot tubs using Dichlor (standard hot tub chlorine). That’s why we call it self-regulating. It goes to work when the hot tub needs sanitizing so there are no frustrating yo-yo chlorine levels. This time-released method is also why less shock is needed to maintain the hot tub. When the SmartChlor Cartridge is depleted the system will flip over as a visual reminder to replace the empty cartridge with a new one..

Comparison

@ease uses up to 75% less chlorine than ordinary chlorine systems so the water feels softer with no bleached suits or smelly odors. No more shocking weekly or after every use. You only shock once a month.Testing is also much easier with one color match for chlorine that tells you when to replace your SmartChlor Cartridge. Only @ease offers the benefits of Fresh Mineral Water and the innovation of SmartChlor Technology.
