Hello,
Attached are a couple pictures of the Spabalancer.
For people with lung ailments, Spabalancer is their only opportunity to enjoy a whirlpool (including bronchitis, asthma, whooping cough, COPD). Chlorine etc only make their illness worse.
For people who like to stay tan long after their vacation, Spabalancer is also great, since chlorine bleaches the skin after just a short period of time.
In addition, the water is softer and your skin doesn't feel dry during or after bathing.
Using it is really easy. Only the first time you fill it up takes a little extra effort. Occasionally I also add Ultrashock by Spabalancer. The two together give you fantastic water quality for about a year (I'm still testing it).
Yours truly,
Cliff H.
