The Dead Sea's rejuvenating and revitalizing powers have been cherished for thousands of years. Cleopatra proclaimed the Dead Sea as her personal health spa. Since then, people worldwide voyage to this oasis of vitalizing minerals to bask in its wealth of natural health and beauty. Extensive research has made it possible to combine the latest sanitizing technology with the ancient minerals of the Dead Sea. Through electrolysis, the machine creates a natural form of chlorine for sanitizing the spa and leaves the vital minerals to be absorbed through the skin for the bathers well being. Soak in the magnesium- and potassium-rich oasis that helps muscle function, nerve cell communication, and cell reconstruction. Cherish the fusion of modern technology and ancient wisdom, a clear harmony of purity, health and beauty. Nexa Dead Sea Minerals are simple to use. When refilling your spa, simply add one bag for every 250 gallons of spa water. Allow the minerals to dissolve, then enjoy the enriched spa environment. To also purify your spa water, use the Nexa Chlor plug-in system in conjunction with the Dead Sea minerals. This will eliminate the need to add packaged chlorine or shock to the spa.
