Transfer from QT

[JurisHP]

I’ve got a 55g QT with nothing in it but live rock. I had quarantined a Tang and treated him with copper until the Ich was gone. He was in this tank for about 90 days (while waiting for new tank to put him in). I stored a bunch of live rock in the QT (while waiting for new tank), and now that the new tank is ready, I want to transfer some of the live rock from the QT to the new DT. Is this risky? I don’t want to transfer Ich or copper to the new DT.

I would not transfer any amount of Live Rock that has been soaking in copper for 90 days into my Display Tank.

Too high risk that copper will get in your display, killing your corals and inverts.
