ACE® Salt Water Sanitising System
Enjoy peace of mind knowing the optional ACE Salt Water System is creating the sanitisers you need to keep spa water sparking — even if you haven't given water care a thought. Only HotSpring® offers this automated, low-maintenance saltwater system that enhances the quality of your spa water.
A Clean & Comfortable Spa
The ACE system uses a patented diamond electrode that creates active oxygen. Because cleaners are automatically generated from salt and water, spas with the ACE system lack the odour of chlorine and require fewer harsh chemicals that can irritate skin and eyes.
Save Time On Maintenance
The ACE system automatically generates cleansers in your spa water. This more hands-free approach saves time, so caring for your HotSpring spa is easier than ever.
Use Less Water
Because fewer products are added, the ACE system allows spa water to last much longer than traditional water care. This means that you will drain and refill your spa less often, conserving water and saving you time.
“We purchased the ACE salt water system and it is so easy to maintain and keep the water clean. There is no skin or eye irritation and the water is sparkling clean.”

Caring For Your ACE System
The ACE Salt Water System makes it easy to care for your spa, so you spend less time on maintenance and more time enjoying your HotSpring. The following videos take you through the simple steps of caring for your system.
Frequently Asked Questions About ACE
Traditional salt water systems use titanium electrodes capable of producing only chlorine. The ACE system uses a unique solid diamond electrode along with two titanium electrodes. The patented diamond electrode increases the sanitising power, while using less salt, and generates 5 different cleaners instead of just chlorine.
The diamond electrode in the ACE system generates high energy active oxygen from water. The active oxygen is the first way the ACE system cleans the water. Once the water is clean, the active oxygen combines with just a little bit of salt to produce 4 more cleaners – chlorine as well as ozone, hydrogen peroxide, and MPS. (Note that MPS generation is dependent on having pH down present in the water.)
The ACE system is currently an option for HotSpring spas built on or after August 5, 2009. Contact your local HotSpring dealer to find out if your HotSpring spa is compatible with the ACE system.
Like bottled chlorine, the chlorine generated by the ACE system is sodium hypochlorite. However, bottled chlorine contains stabilisers like cyanuric acid. When bottled chlorine is repeatedly added to spa water, the cyanuric acid can accumulate over time causing irritation to the skin and eyes. With the ACE system there are no stabilising acids added to the water – so the water is gentler and more enjoyable.
The ACE system cleans the water with Active Oxygen first, without creating chlorinated or brominated byproducts. It is these byproducts that ultimately lead to the strong chlorine or bromine smell often associated with traditional spa water care. It is less likely you will experience any strong chlorine odour when using the ACE salt water sanitising system.
The ACE system automatically generates powerful cleaners and the required sanitiser - chlorine - needed to keep spa water clean and safe. In doing so it eliminates much of the daily or weekly water care requirements of traditional systems. As the spa owner you still are ultimately responsible for the safety of your water and must be sure to do all of the following:
Balance spa water at start-up and keep the hardness level near the target of 50 ppm
Ensure the chlorine level is in the EPA recommended range of 3-5 ppm
Test water weekly with a test strip. Balance and adjust use level as needed
Rebalance and confirm use level, every 30 days
Clean the diamond electrode cell every three months
