Thanks guys, I am going to run bleach through the system for 24 hours. My QT is a 4x34 gallon system - spraying is not really an option.
The experts can correct me if I am wrong, but the most important part is everything completely dry for more than 24 hours. Meaning every nook and cranny dry and that way for at least 24 hours. I don't believe any of these parasites/diseases survive without water for very long..
