The problem is that you don't know what minerals are in the lava rock. Personally, I would avoid it. JMO

I'm using a 20 something lb lava rock in my reef, and dont have any problems that can be attributed to that sort of thing.
I say go for it.

couple of other concerns, Lava rock is very sharp and can damage the jaws of fish that graze the rock. Also think of where it came from- heavy metals>?????

My LFS said that it leahes phosphates, heavy metals, and some bad minerals, and I have to agree. Like jks1 said, think of where it came from.

Well all I can say is that when I had a 29 gallon reef tank well over 30 years ago the only thing we had was lava rock.

As far as I can remember I never had any problems with it and it was a beautiful tank for over a year and a half and then got broken in a residence change.

I had a flame scallop, shrimp, jawfish and they all did very well!
