Didn’t seem to work.

I had thick scale on my swim spa, and used this product, without results.

Really helped to clean out the spa jets!

It is what it is: a scale treatment for your hot tub. Our local place is closed for renovations, so I have to get our chemicals online, but this is just what I needed. It is working great to help get the hot tub up and sparkling for the winter season. It is compatible with hot tubs that you treat with bromine and chlorine, so if that's a question anyone has, you can rest assured. Our hot tub is coming along and looking great!
