Often base rock tends to be very solid and not the best rock to be used for all your tank. Most live rock is porous, while base rock often isn't.

base rock is solid??? base rock is dead live rock. both come from the same place. the ocean. and are made up of the same components. its just as porous as true live rock just without the coraline,bacteria,hitchikers and other algae.
