I was hesitant to buy a spa since I had managed a pool for many years and found it challenging to keep all the chemicals in check. I also suffer from very dry skin in the winter. When we purchased our spa, it was recommended that we use SilkBalance. The use of SilkBalance made the maintenance of the spa easy, and despite the fact that my wife and I use the spa daily, our skin is softer than it has ever been. SilkBalance has certainly made the use of our spa an enjoyable experience.
