I have a lot of live rock between three tanks and don't have any idea how many pounds I have. How would I tell how much I have?
Weigh it.

I'm asking because the important thing isn't really the weight, it's the surface area. Some rocks are much denser and have less surface area per lb. nice dead coral rock has way more surface area for the BB to live on.
I would take 1 lb of porous coral rock over 2 lbs of man made rock with no cavities. And they'd likely be similar sized.
Not that all man made rock is bad. I have some nice stuff as well.
Doesn't a fish only tank take less live rock than a reef tank?
