Perhaps you're missing the point of austinsdad's post, or maybe I'm giving him more credit than he deserves, but...
You say you don't have the money to set up a QT. But yet you have the money to buy a cleaner shrimp or "reef-safe" medication.
A hospital tank doesn't have to be expensive. It can be a Rubbermaid tub, a heater, and something to serve as a biological filter. Granted, that probably adds up to more than the $20 for a cleaner shrimp, but it shouldn't be more than $50. And doing hypo really doesn't cost much of anything - you're just treating the fish with very low salinity saltwater... the same saltwater you already have.
Seems like there are a lot of recent posts from folks that don't have the time/money to do what needs to be done to truly cure their fish. You might want to glance over some of those threads and see how things have worked out for them, if they've updated them at all. I realize that if the money isn't there, the money isn't there. But throwing money away on things are just plain don't work isn't helping you out in the long run. You'd be better off just saving the money and continue hoping it gets better.
