Since reefsquad doesnt have much more insight on this, I have an idea,
@GoVols what do you think of this?
I have my other qt tank empty and sterile currently, waiting for next batch of fish to come out of copper eventually. Tank is same volume as my invert/coral qt tank.
What if I filled my qt1 tank, added couple piece of live rock from my displays to it. Then transfer the coral I'm really trying to get out of that invert/coral qt tank. Dip prior to entering qt1, and visually observe for flatworms? What do you think?
