Experience the Best Spa Water Possible

The Difference Is in the Diamonds

“It’s a wonderful spa. I love the ACE system, too. I never have that “chlorinated” smell on me after I get out, and my skin feels smooth, not dried out or itchy.”
– Hot Spring Owner

With easy to care for spa water that looks, feels and smells great, you’ll spend more time in a Hot Spring® spa.

The exclusive ACE salt water system is an option for all Highlife®, Highlife NXT and Limelight® Collection spa models.


Enjoy fewer chemicals and more natural spa water.

Only the ACE system creates “active oxygen” and other powerful cleaners from just a little bit of salt and your spa water. So, there are fewer chemicals added.

How it works


Spend less time caring for your spa and more time creating memories.

The ACE system automatically generates chlorine and other cleaners for a set amount of time each day, based on your input. So the system is keeping your spa water clean, even when you haven’t given water care a thought.
With proper care you will drain and refill your spa less often, because the ACE system helps spa water last longer – up to 12 months.
Caring for your water

Caring for your water


Forget about the dry skin, irritated eyes, or chlorine odor.

Using patented diamond technology, only the ACE system eliminates contaminants that impact water quality. With silky soft spa water that looks, feels and smells this good you will use your spa more often.
