Dear SilkBalance, My wife and I have had our hot tub for 3 weeks now and have been using SilkBalance ever since. The water is clear and clean and it leaves our skin silky soft. There’s no harsh chemical scent. Our 2 boys (13-10) love going in the hot tub with us and look forward to it every night, plus we don’t worry about their skin because of SilkBalance. The whole family loves SilkBalance! Marc and Holly Lalonde Ontario, Canada
