We have now had Silk Balance for 6 months, and it has improved our hot tub experience for the whole family. My husband and myself suffer from sinus congestion, and we now can enjoy our hot tub without getting congested from the chemicals as well as not having to take showers immediately after to get the chemical smell off our skin. Silk Balance has also allowed my kids to enjoy the hot tub for not over drying their sensitive skin. Thanks to Silk Balance, we can enjoy our hot tub more than before. The Powers Family
