I feel for you. I've been lucky and not had any issues with disease since my freshwater days growing up. I remember treating the fish then with something from the pet store, but I've slept many times since and couldn't tell you what it was. If you haven't thought of it already, make sure to have some PVC pipes and elbows in the QT for the fish to hide. I've never ran even a bowl of sand in a QT tank, so I can't help you there, but agree that any dry/dead reef sand should be fine.
