Love Silk Balance. Makes the tub smell much better than conventional chlorine only tubs. We feel silky smooth after hot tubbing. Best perk is I tend to have athlete’s foot from working long days in shoes. Silk Balance has really made a difference curbing my athlete’s foot challenges. We built a first class hot tub area. Third floor off our master bedroom. Great decking, outdoor shower, stained 8 foot privacy walls. Silk balance compliments our first class design. Have better pics available.
