Hey, so I had a question regarding BRS's dry rock. How exactly do they ship their rock? As in, say I order 40-50 pounds of dry rock (which is what I'm planning btw), would they send like 3-5 big pieces or do they send like 15-20 pieces of rock? I am planning the small foundation rock, the shelf rocks, and the reef saver rock. I just would like to know how they would send it to me, in a few big pieces or a bunch of small pieces (which i prefer). Thanks!
