Our hot tub came with the purchase of our home, and we became first time hot tub owners. We spent almost a year trying to keep our pH balanced and always had skin irritations with use of the hot tub. So, we didn’t spend much time in enjoying it. Then, we tried a new dealer and they talked to us about SilkBalance. We were hopeful but skeptical at first, until we started using it. I couldn’t believe how easy it was to use and that it actually did a great job of keeping the pH in balance. Also, love that our skin feels soft and clean after being in it, and our water always looks clear. Now, we are finally enjoying our hot tub every week! Very thankful for this product!
