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.

    This is the only system I have ever used. When you first get your tub and it had heavy use I felt like it was difficult for the system to keep up. Now that use has slowed I get at maximum 3 weeks per SmartChlor. I also found that my retailer was not familiar with this system and didn’t explain it well. I had to do a lot of research to understand it. I have also found it difficult to find retailers of the product without having to special order, travel far or pay for shipping. The kit needs to be on Amazon. What nice is that the product is out of the way. I cannot imagine having a floating system.

    I have a had a hot tub now since 1999 and have used practically everything offered; bromine, chlorine and baquacil, etc. This is by far the easiest I’ve ever used.
