birdman lava rock is not man-made rock. In fact lava rock is very porous.

I would not hesitate buying Walt Smith products at all. I can not say the same thing about Caribean rock from Tampa bay Saltwater or other gulf rock supliers, although TBS rock is a good rock I personally dont care for it. Please dont confuse that with a slam to thier product because it is a good product. Its just personal taste on the way its cultured and a few other reasons not pertaining performance persay.

I have yet to see
man-made rock that is as porous as natural rock. Good natural LR is like a sponge, you just can't make it like that from cement. I'm all for "Eco-friendliness" But you will need more man-made rock to do the same as good porous natural LR. So yes it is pertaining to performance.
Ganja wanted to know if there was a difference in the two rocks and there is... a big differences!
And ReefDoctor I did not slam anyones product!!! I was giving my opinion. I said...
I would stay away from man made rock
