Thank you very much for introducing us to Spa Marvel. We have been using this product for three weeks now and it is amazing the spa is crystal clear and the water smells and feels fresh and clean. We have tried many other options over the past 3 years and this is the only product that that has not caused my skin to become irritated. We are happy that we can now use our spa on a daily basis and enjoy the experience that once enticed us to buy a spa 3 years ago. Thank you, thank you and thank you again.
