you know so i'd have like one main pillar sort of in the middle but a little off to the left or right, then like one half that height all the way in one of the corners, and then a few small little structures here and there. how do you do that? I read you're not supposed to stack live rock cause there needs to be space for water to pass through everywhere so there isn't die off. How do people create huge reefs with it if they don't stack it?
