Cut it down to size?

[jmatt]

So, I've purchased a few zoas, nice sizable chunks with many heads. But they're on a chunk of rock that I don't necessarily want; it puts them a few inches closer to the surface and seems like it will prevent them from easily propagating outward. I mean, ya can already see the ones on the side extending way out to get some light.

So, how does one deal with this situation? Do I need a bandsaw to cut away the unwanted rock? (which I'd probably put in the sump or sandbed)

Yeah, although they'll probably extent to cover the rock eventually.
