Too much overflow for me. I wouldn't want a box inside the tank that went side to side, adn I wouldn't want anything hanging off the back. 1 or 2 vertical stacks inside is much cleaner looking, IMO.

I have a center in my 140. Would much rather have it on the side. seems to be in the way in the middle.

in a small tank it would be very imposing.

my 90 is in the center and i dont really like it much either.

If I go with the centre, I would build the overflow box with angled sides, I think that would make it blend more. However, my plan is to have an open middle tank and this would cut 6" out of the centre area. Maybe 1 or 2 corners will be better. I think for my needs, one on the left corner will do it.

I had a V shaped center overflow in my 180. It was ok, but I still prefer the corners better.

But thats wall built, where I dont view in the ends.

I just made a smaller sized rock wall around it. Why not do something like a homemade rock plaster on the overflow, then one could still leave the center open.

I also thought the center V would be better on my current 5ft. tank, with two halides, but on a 4ft. guess it does not matter as much.
