I recently purchased my Hot Springs Prodigy in December of 2012. I have used hot tubs before and most of the time experienced dry and itchy skin. I was worried that the same thing might happen with my Prodigy. I have used SilkBalance from day one and the water has been perfect! SilkBalance makes my skin feel smooth & soft and eliminates the need of any harsh chemicals. I will never be without my SilkBalance.
