This is the manufacturer’s description of the Nexa Spa Natural Chlorine Generator. We do not endorse or assume any responsibility for the accuracy of any statements made in the manufacturer’s description. Manuals & Notes at bottom of page.
Nexa Spa is simple to install in about 10 minutes, without tools or any modifications to your spa. It is completely compatible with ozone, and in fact enhances the water quality of ozonator-equipped spas. As with any system, properly balanced water is essential.

The Salt System: recycles itself You’re probably wondering how often the salt needs to be replenished. One of the beauties of these systems is that as the hypochlorous acid is used up, the chlorine recycles back into salt. So with a salt chlorine generator, the salt only has to be topped off occasionally due to hot tub water splash out, and replenished when the water is changed. Very economical! |
Salinity Levels: lower than you think
When we think of saltwater, the ocean usually comes to mind. Seawater has a strong salty taste of course, and it can cause metal corrosion. So you might be wondering if salt systems are safe for spa equipment. Fortunately, the levels of salt used with Nexa Spa systems are very low by comparison, and safe for equipment.* The table below shows some approximate saline levels to give you a perspective:
 |
Salinity Comparison – parts per million | |
| Ocean Water | 35,000 ppm | |
| Human Tears | 9,000 ppm | |
| Ability to Taste Salt | 5,000 ppm | |
| Modern Salt Pools | 3,000 ppm | |
| Nexa Spa System | 1,500 ppm | |
In fact, at 1500 ppm most people cannot even taste the salt. The salinity and chlorine levels are easy to check.
Dead Sea Minerals: a better salt
Your choice of salts is very important. Common table salt, rock salt and ice-melt contain anti-caking agents and other additives and impurities which can foul the electrode plates of a chlorinator, so avoid those types.
|
We offer a special grade of authentic Dead Sea Mineral salts for the Nexa Spa, refined for use in salt chlorinators (or which can be used alone). This natural product contains not only the necessary sodium chloride, but other beneficial minerals not found in common salt.

The Dead Sea contains many naturally occurring minerals, some found in no other sea, lake or ocean. Dead Sea mineral baths have been recognized since ancient times to impart a relaxed feeling. They nourish the skin and invigorate the circulatory system, while easing discomforts, everyday aches and pains and muscle soreness. They can turn your spa into a backyard oasis.
Your home spa is the perfect place for you to combine the many benefits of Dead Sea Minerals together with modern salt system technology. |
NOTE: The Nexa Spa Natural Chlorine Generator uses increased salinity to provide more chlorine output. (1,000 – 5,000 PPM, with 3,000 PPM stated as the ideal level in the Nexa Specifications Sheet, CLICK HERE. An optional timer is also available for the Nexa Spa Chlorine Generator System. They also have a recommended Salt System Pro Supplies Kit for an additional $79.95.
The optional timer is a must have since it will allow you to program the unit to produce chlorine throughout the day for different amounts of time to ensure chlorine is available when you need it.
In reality, I have yet to see any measurable chlorine production from salt levels below 1,800 PPM. All units use the same technology with varying plate size quality. There is real test data from an ORP/pH controller on our test data page.
The Nexa Spa System encourages the use of Dead Sea Minerals which is composed of 12% Sodium Chloride and the rest is 33% Magnesium Chloride, 24% Potassium Chloride, 5% Calcium Chloride and other inert substances.
I have used non-iodized table salt, 99.8% solar salt, Morton Canning & Pickling Salt, Himalayan Salt and rock salt with NO ISSUES. Dead Sea Salt takes a little more then the others due to its lower sodium chloride content.
