This is something that I've always wondered about with in-wall applications. Do you plan on doing anything to accommodate the difference between the face of the aquarium and the face of the wall? In other words, the tank looks recessed, and I'd be looking to do something with trim to make it look more seamless. It probably doesn't matter on such a large aquarium - yours looks amazing either way. I was planning on doing a 90 gallon in-wall and wanted it to be flush.
