HTH is my go to brand for all my hot tub (inflatable hot tub supplies)! The products are doing what they're supposed to do to keep the hot tub clean and safe for my son which is all that matters. After using HTH Alkalinity Up in our inflatable hot tub, I can confidently say it’s a fantastic product for anyone looking to maintain optimal water quality with minimal hassle! It's not often we need it but it's a great product when needed. And a fantastic price HTH Alkalinity Up has become an essential part of our tub maintenance routine. It gives peace of mind knowing the water is always comfortable, clean, and ready—whether we’re enjoying a heated soak or cooling off after a hot day. For anyone with an inflatable hot tub looking for an efficient way to keep alkalinity in check, I highly recommend it.

Works well, we use these to test our hot tub PH levels. They work just as described, and they last us about a month.
