This is exactly what I would have recommended. I was about to post it and I saw that you had already thought of it. Maybe a piece of 1/2" Lexan set in the wall in front of the tank to make sure that mischevious teenagers don't play pool without you knowing...and trash your expen$ive tank with a bad/misplaced shot. If the Lexan gets scratched or cracked, it is replaceable. Just don't clean it with Windex. Windex causes crazing in Lexan.
