I'd be more concerned about the 2" bulkhead in a 5" overflow, minus the glass that's probably 4.5", OD of bulkhead = 3.875 so clearance on each side is only 5/16" provided it's perfectly centered and not including the clearance needed for the silicone bead. Not something I would attempt but then again those concept guys are crazy in a good way

Personal preference is external. I like the bean animal but there's a science to the depth of the overflow box and the piping size and where you run the plumbing. My one attempt was a full coast to coast external. It was about 5" deep but didnt run a ton of flow through it. I was able to tune it so the water ran about 1" below the box height. This resulted in a quiet overflow. My current overflow is a 12" deep internal box and the water is running about 2" below the box height. The way I got this tank I had to run the plumbing at the top of the tank and elbow it down to the bottom of the box so unfortunately the water hits the piping and makes quite a bit of noise. It's 1-1/2" plumbing and running about 3000gph. The issue is if you close the gate valve a bit to raise the water height so its quieter it starts running more water down the balance pipe and that makes more noise. Its not just drill and go.

Well after a discussion with my wife I have to settle with an internal overflow. I don't get anymore space in the house for my tank.
It's her house to and she wins this one. It would push my tank out a further 11". I have alot of confidence in Dave and Denny at Concepts and Paul from OC and i'm sure the pros wont stear me wrong. |

My external overflow on my 400g was no more than 6" out from the tank and I had 1.5" bulkheads inside it. I didn't read the entire thread but 11" seems excessive no?
My current overflow is internal. The box is only about 4" in length from the back of the tank and it only goes down about 8" I believe so doesn't affect where fish swim too bad. Then my pipes exit the back of the tank and 90 down so you have a thin box in the tank and the tank only stick out from the wall the depth of a 90 fitting. |

I should have explained better. My tank right now is 29" wide and 5 1/2" away from the wall. If I went with the 6" external overflow which would be ideal, my tank would stick out 6" more so a total of 11" from the wall.
