We are the Collins Family. Pictured our my sons Henry and Cooper. We use our hot tub regularly. In fact, I like to think of it as a second bathtub minus the soap ;o) I feel confident the hot tub is safe and clean for our daily use. We have been using SilkBalance for about a year. I like how simple the start up process was and the upkeep. I especially like that we can all climb right into our pajamas after the hot tub with out feeling dry and itchy from chemicals.
