There are several things that I like about SilkBalance. The elimination of water testing and balancing I find to be a real plus since all you need to do is add SilkBalance once a week and forget about it. The water in my hot tub is smooth feeling, stays crystal clear and odor free. SilkBalance is a hassle-free way to maintain my hot tub water. Besides periodically adding SilkBalance, all I have to worry about is bacteria control.
