Hi Helen, I wanted to let you know I have refilled my spa and I'm loving it! I seriously think my spa is the best purchase I've made since buying my home. I want to thank you and David for all your help in choosing the ideal spa for me, making sure I set it up right and of course always being available for all my questions! I also love that I'm not using any chlorine or chemicals in my spa and also want to thank you for your support of the Nature Spa products.
