We’ve had our hot tub for about two years now. The first year we were using other chemicals. The water was always cloudy, our skin was dry and felt like there was a film on it once we used the hot tub. We hated using the hot tub! Once we tried SilkBalance, we were in love! Our water stays clear now, our skin doesn’t have that same dry, filmy feel to it anymore. I highly recommend the product! We finally love using our hot tub thanks to the difference SilkBalance made.
