Keeping the alkalinity up, balancing out the other chemicals, and making my kid and dog happy
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.

Perfect for Alk Up!
’ve been using this with my Coleman SaluSpa, and it’s done exactly what I needed it to do. My alkalinity was a little off, and this brought it back into range pretty quickly without a lot of guesswork. It dissolves well and doesn’t leave any residue, which is always a plus when you’re dealing with spa chemicals. Once balanced, I noticed the pH stayed more stable instead of bouncing around, so I’m not constantly having to adjust things. The container size is also practical—you don’t need a ton each time, so it should last a while depending on how often you’re maintaining your water. For the price, it’s a great value and an easy addition to regular spa maintenance. If you’re running a SaluSpa or similar setup and need something reliable to keep your water balanced, this does the job well.
