Has anyone ever tried making something similar to this:

But for a saltwater tank??? I'm converting one of my tanks over to a fish-only saltwater tank. I planned on using the same vinyl guttering/aquarium safe silicone used in the plans (I've done this a bunch of times in freshwater tanks), but rather than sticking lava rock to the gutter material, I was going to use Crushed Coral instead, making it look like 1 big piece of coral w/holes in it.
I think it would look awesome when I was done, but I was curious if this was a good/bad idea, and why???
