I Love Silk balance! It is a great product and certainly helps our hot tub. I am the person who mainly does the weekly maintenance on our tub and I believe that it helps keep the water clear and clean. Our neighbor is always having trouble getting their tub to balance out and not be cloudy, we have no problems with it when we use Silk Balance. We also have no issue with it smelling or projecting an odor. It is always fresh and clean when we are ready to use it. I highly recommend the product to anyone who is considering getting a hot tub. It has made the maintenance of our hot tub much simpler. We had another hot tub preciously and we struggled with keeping it balanced. Love Silk Balance.
