Thanks for the great customer service you provided when we were dealing with my skin rash problem. The rash appeared shortly after we got our new hot tub and it was very frustrating trying to deal with. We followed all of your helpful suggestions and are now enjoying our lovely, sparkling clean hot tub with total enjoyment. My skin is so sensitive that I was wondering if I would even be able to use the tub regularly. Spa Marvel is proving to be the solution for us and we are more than pleased. Thank you so much for your assistance.
