It really works great.
I have a hot tub at my cabin rental. For years I used this liquid calcium booster. Then I ordered what I thought was the liquid booster from another company and it just wasn’t bringing the hardness up. I returned to the liquid which does an excellent job of bringing the hardness up where it needs to be.
