They list it as <25% muriatic acid. Presumably the acid concentration varies somewhat from batch to batch. Assuming it is 22% is probably close enough.

I checked that link and it is not sold at any Home Depot in a 50 mile radius for me. Where else can I buy the 31% concentration of Muriatic Acid?

Crown Muratic Acid Next???

Sorry to bring this old thread back!!! I could not get my normal MA from Tractor Supply. So I sent my kid to Lowes and he came back with Crown Muratic Acid Next.... Don't care about strength... Simply want to make sure before I open that it is SAFE to use in the pool... As in is it only Muratic acid? The lowes spec information says not safe for Salt pools which is why I ask.....
