The goal is to have the least plumbing or wires showing , I would like to build some fake fiberglass rocks on to the walls to bury most plumbing and at the same time create shelves for the tunzes and to place some corals on the walls, the middle section of the back will have a dark faded background coved with a piece of thin glass to simulate continuos depth.
Let me know what you think, or if you have any suggestions.
