Built-in Hot Tub Water Care That Puts You At Ease

Self-regulating. Only Shock once a month.

Introducing a breakthrough in sanitizing that comes ready to use on select hot tub brands.  @ease with the innovative SmartChlor® Technology and Fresh Mineral Water® benefits offers a complete sanitizing system that’s time released to meet the demands of any hot tub up to 600 gallons. The result is crystal clear water for weeks at a time using up to 75% less chlorine*! So your hot tub is always ready to use.

Only available in the U.S.


  • Kills bacteria with up to 75% less chlorine* than ordinary systems.
  • It’s so easy you only shock the hot tub 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.
  • No faded swimwear. No chlorine smell.
  • No Mess No Guess. No Stress. No daily or weekly maintenance.

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.

When the SmartChlor Cartridge is depleted, the SmartChlor Out Indicator on the @ease Test Strip will be a light green. Simply replace the empty cartridge with a new one.

This technology is so unique it has its own testing method that’s easier than standard test strips.

    When it works, it can be nice. Like others, I only get two weeks out of it. If I push for more, the water turns quickly more often than not. Far too little time for the price.
