When you get bored......

Get a tinted black glass...dark as you can for the false wall. Then use sch 80 grey pipe in there and you won't see a thing and you'll have a nice glass wall wet side...easy to clean.

I did something similar on my first tank and really liked it. But I had a piece of black plexi siliconed to the wall...wet side. Thing had a bit of warp to it which was noticeable.
