After years of going to the dermatologist, going through bottles of bromine, and chlorine, we decided to close our hot tub due to lack of use. It was only after talking to our spa dealer that convinced us to give SilkBalance a try. This is an amazing product that truly lives up to its claim. The water actually feels silky and skin rashes are no longer an issue. Thank you SilkBalance for giving back to us extended years of enjoyment in our hot tub.
