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.
