SilkBalance has become a magical recovery to my spa experience. Keeping my water balanced and comfortable had become like a junior chemistry project. The frustration of unpredictable results while trying to keep all parameters normal had taken the fun out of having a spa. Then I was introduced to SilkBalance and all of that improved. The easy use of this product and the wonderful quality of water is indescribable. It has replaced the use of about half-dozen products. The water is extremely smooth on the skin and has a clean aroma. SilkBalance is a spa-saver!!
