Well, you don't have a lot of acro, so you would have been best to toss them, wait however long it takes for AEFW to die, then start over. You can treat if you have a lot of expensive pieces, but yours don't look healthy enough to get through what would be needed. Screwed is all relative, so wouldn't have been terribly painful
Still not sure what's going on, IMO acropora are no more sensitive than other SPS you have. So it does appear to be something specific to them.
