Why Salt Water?

After many years of successful use in pools, salt water sanitization has now become available for hot tubs! Salt water sanitization works by passing regular table salt (sodium chloride), dissolved in water, across a low voltage electric current. That current energizes the salt molecule, which combines with the hydrogen found in water to form usable chlorine sanitizers. The eZ Ultra Pure salt system from Hydropool takes that same principle and instead uses sodium bromide to create usable bromine.

Why Bromine?

Bromine is an element that is very similar to chlorine, and has many advantages over chlorine when used in the conditions found in hot tubs. It is a more stable sanitizer and will not evaporate like chlorine at the high temperatures found in hot tubs. Bromine will also maintain its effectiveness over a wider pH range, staying 85% effective at a pH of 7.8, where chlorine drops to only 30% effectiveness!

No more chlorine odor! The eZ Ultra Pure salt system produces bromine, so there’s never the harsh scent of chlorine to deal with. Since it produces pure bromine, without the additives and binders found in traditional chemicals, the water will also have a softer, more natural feel to it.

Low Maintenance

After the simple start-up procedure simply fill your spa with water and add the convenient eZ Bank sodium bromide solution. The eZ Ultra Pure salt system will then begin to automatically generate and release bromine into the spa water, rapidly destroying any microbiological contaminants such as bacteria, algae, and any organic matter given off by bathers.

No more confusion about chemicals! You don’t need to wonder what chemicals to add – once installed, the eZ Ultra Pure salt system generates the proper amount of bromine for your hot tub. Adjustments to the bromine level can be made right at the keypad! Since there are none of the additives and binders found in traditional chemicals being added to the water, salt water hot tubs only need to be drained 1-2 times per year, saving you time and money!

Away for a while? With the eZ Ultra Pure salt system you’ll still enjoy a clean and clear spa when you return, even weeks later! While you’re away the system will continue to generate the perfect amount of bromine, based on the setting you select.

Why not spend your leisure time enjoying your hot tub, instead of maintaining it?


Will the sodium bromide evaporate?

No, the only way the sodium bromide is lost is through splash out. Small doses of sodium bromide will need to be periodically added as fresh water is introduced. The keypad will display a warning if the sodium bromide level decreases.

Will the water taste salty?

No, the level of sodium bromide needed is less than 10 times the ppm (parts per million) of salt found in the ocean, and well below the threshold that humans can taste.

Does the system need to run 24 hrs a day?

No, the system will only run when the hot tub is filtering. In order to properly sanitize the water with a salt system you should set your hot tub’s filtration to run between 8-12 hours a day.
