Free live rock most likely infested with something ugly

[gregzz4]

Shutting down a QT tonight
1 piece of rock about 9x5x5
Lots of pods and coralline, some green palys, aiptasia, lettuce and bubble algae --- and something that likes to kill fish ... either a nasty strain of MI, or possibly Velvet.
Not sure at this point

Either way, it's going in the recycling bin tomorrow night unless someone wants to throw it in a tub of water for a bunch of months to save the pods and algae and let the nastier stuff die off.
