Has anyone done a rock wall with marco rock. I have his rock in my 75 and its awesome. Im planning on upgrading to a 150 cube and want to do a rock wall on the back side cause its going to be up against the wall. I will need pond foam to fill in the hole I know casue I dont want a bunch of crap to get behind the rocks and rot. Just seeing if anyone had any pictures of how they did it or a link to their thread. Also if anyone has any they are looking to sell I might buy.
