I recently purchase a new hot tub and decided to use Silk Balance as recommended by the salesperson. I have used hot tubs at hotels, cruise ships, etc. and was a previous hot tub owner but this is the first time I have used Silk Balance. I really like the way Silk Balance makes my body and skin feel after I use my hot tub. My skin really does feel silky smooth, refreshed, healthier and smells fresh instead of smelling like chlorine. I really am happy that the sales person recommended the silk balance. It is true, Silk Balance will keep your water clear and clean and you will look and feel better after each use. I look forward to receiving my next bottle.
