I am a first-time spa owner. The reason I put off this purchase for so many years is the complicated issue of chemical balance in the water. Bullfrog Spas of Ogden recommends using SilkBalance with a minimum of other chemicals. The water stays beautifully clean and clear with relatively little care and the SilkBalance is a real boon to a family of people who have dry skin. I have no intention of trying the more complicated system when SilkBalance gives me more than I dared hope.
