As first time owners of a hot tub, silk balance has made learning how to care for our hot tub easier than expected. There is no strong chlorine odor and it leaves your skin feeling smooth when you are done enjoying the tub. We use this product weekly along with shock to keep our new “toy” running smooth. Silk balance takes the worry out of hot tub/spa care and gives you more time to sit back, relax and enjoy. Thanks for making our introduction to spa care so carefree.
