Well, when I was taking out the old gravel, I made a big mound in the middle left side so I could syphon the rest of the water out of the right side. I walked away, came back and thought that it looked interesting. Figured I'd try it out...tired of just flat, or sloped(front to back etc) substrates. I liked the one mid lower, and the higher side. I was thinking of high on both sides and do a valley but figured I liked the unsymmetrical look about it.
