I saw this idea on aquarium web portal. The backgroung wall has two characteristics: it looks nice when is made perfectly and is HEAVY. It consist from four pieces of glass and flat rocks. All fixed by silicone. The first one is from limestone. I made a few years ago and it still needs some patches. The second one is sand stone. Looks slightly better I hope. Maybe someone else here could try this. Enjoy.
