Well, not QT'ing always presents some risk. Recently I've read so many horror stories, and evidence that certain "bugs", etc. seem to be on the rise, that I would look into dipping any new additions, since I don't have room or equipment for QT'ing coral. I know Salifert makes a product that people use to dip new additions in. It's sometimes combined w/ one or two other things. I've read about this primarily being done w/ stoney coral, but I assume the method for soft coral is the same. Something you can look into if you feel the need.
