We love the SilkBalance for out hot tub. This is our first Hot Tub and we were afraid that the maintance would be difficult. We are also on a well so we were worried about the drying of the skin. When we use it you do not feel like your skin is dried out. We will continue to use the SilkBalance in our spa because it is just easy. Thank you, The Bowler’s Glencoe, Mo.
