I just got my first order from http://www.hottubeverything.com. Thank you all for your help. I switched to the product they recommend on the website called spa ease. I like it better. Seams to be more powerful and I don’t have to use it as much. I wasn’t really using a lot of chemicals to begin with, but I think I will stick with this product from now on. They also have a discount for Barefoot spas customers which was a big plus.
