Returns: above or below internal overflow box?
There are already holes on my new to me 120 gal that I plan on using for returns. I'm going to have an overflow box put on. Where do I need the overflow box? Above, below, or same height? Does it matter? It has a slotted weir not teeth but slots. Does the height from the holes to the teeth matter?
