@ease ® In-line (Chlorine) System

Introducing the innovation of SmartChlor® Technology - the self-regulating chlorine that works together with FROG minerals in the easy to use @ease In-line 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.

•Kills bacteria with up to 75% less chlorine* than ordinary systems.
•Shock just once a month.
•SmartChlor cartridge lasts up to 4 weeks depending on hot tub usage. Recyclable when empty.
•The Mineral Cartridge lasts 4 months or whenever you drain your hot tub.

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 is no frustrating yo-yo chlorine levels. This time-released method is also why less shock is needed to maintain the hot tub.
