Foam Aquascaping?

[jgoldsney]

I have done the back of my tank with the 'Great Stuff' expanding foam. What I did was make a base out of egg crate with some egg crate shelves zip tied to it to make ledges. I then sprayed the structure with foam. To get ridd of the "turd" look I dropped handfulls of sand and coral chunks on it while it was still wet. once it dried I sprayed it with multiple coats of Krylon Fusion black paint. It is now quite covered by coraline and you can hardly tell that it is not rock.

Well it looks like I might not do this after all. Scavenger who posted here and built a foam wall seems to be losing his fish for some unknown reason.
I HATE LOSING FISH.
So I think I'll just build a nice back wall out of live rock. At least we all know that it works
Thanks everyone for your input.

Sorry, it wasn't Scavenger it was JGoldsney

Anyway, thanks all

Yes but he is 1 out of how many have done this in the past?
I think there might be something else or working with that to create a fish death zone.
