Getting rid of unwanted polyps?

[Reef This]

I recently had this rock that had about 5 polyps on it when I got it. 2 years later, it probably had 50-70 of them. Just little brown button polyps of some sort.

My question is, I've found it moved to another rock, and I removed the original rock and gave it to a local fish store for a reason. I don't want them spread all over my tank. Obviously, that didn't work. :eek2:

How can I remove them? Will Joe's Juice get rid of them? Do I just need to cook the piece of rock? Anything?

I hate to kill them, but I don't want them all over my tank, and the rock is an awsome piece in a C shape about 11 inches across. Sits up wonderfully for an arch piece in my tank.

Would you like to borrow my flagfin angel? He recently discovered a piece of rock with a few baby polyps popping up (I was all excited, I love hitchhikers), ate them all pretty quickly

Seriously though, anything that will kill Aiptasia should work; kalk, JJ, etc. If there are enough of them you could also chisel them off the rock (IME easier than it sounds), glue them to another rock and sell/trade the frag but it's more work
