Ever since we started SilkBalance, my 11 year old son has joined us in the hot tub. He complained of “chemical” smells with our previous product, but has no issues now. SilkBalance lives up to its name. It makes your skin feel silky, and it help balance the chemistry of the water so I don’t run the risk of cloudy water. We love it! Rene Campagna, Spokane, WA
