setting up 400 gallon

[NVfishman]

I just ordered a 400 gallon tank 120x 30 deep x 27 tall. I am alittle concerned with the length not getting enough flow and placement of the overflows

I am thinking 2 back overflows as the tank will be against the wall.
These will be spaced 3 feet apart. How big should those be 8,12,16 inches. I am going closed loop but no crazy holes on the bottom of the tank except in the overflow boxes.

any imput would be great

large tank bigger is better in my opinion..

I agree. Personally, I would go as large as possible to insure adequate skimming of the surface.
