I'm sick of the regular black backgrounds. I'd like a clear panel for my next tank, but it will be hard to hide all the plumbing. So I'm wonder, has anybody use that speckled/textured spray paint for a background? Any pics? 
Thinking of mixing a few colors, like the gray, brown, and black versions. Thoughts?
