Why so? Didn't tehy ahve the pump on hand? Did they think a Sequence 5800 was going to be used
The bulkhead size doesn't matter
unless it backs up. I use the bottom of the OF as my waterline judge. My tanks almost always push a 1/4 to a half inch above that so planning on it being the water line gives me some wiggle room.

I hear you Gresham, I was just trying to come with the reasoning as to why the canopy would sit that high, Chris must have his reasons, no? He knows what he's doing I hope.
Those overflow boxes can handle a TON of flow which would push the water level up much more than is it being pushed currently.
