Don't stress we'll be able to figure it. Looks like one drain per overflow. Correct ?Yes it has small boxes in front of the overflow pipes. Maybe 6”? Not the full length kind I see on most tanks.

Ugh, I can’t get a picture without glare. The biggest downside to having my tanks in the sunroom:/
Unlike the picture in that video, the pipe for mine is in the back. So I’m not sure how the sound will be going through it. I really wish the guy I bought the tank from would have been home for me to talk to. I really wanted a rundown on how he had it set up.
