Nope, never. I don't use medications unless I have to. Most are pretty hard on fish. I couldn't remember the active ingredient in Aquarisol, so I Googled it- looks like copper sulfate. This will nuke any inverts you have.
It's been my experience, overwhelmingly, that salt and heat is much easier on fish than medication (including plecos, loaches, cories, etc.), and is just as effective as meds when treating ich.
