Help with QT, Coral Beauty with cloudy swollen eye

[WhoPoopWrasse]

If your display tank has no paracites, just put the foam block that goes into the QT filter in you display sump and leave it there a few weeks, then set up your QT with the foam block that has been collecting everything it needs to cycle your QT. Once you fill it with water from your display, your QT is pretty much ready to go! Then go out and buy your fish. Don't EVER risk contaminating your display with an unQTed fish!
