Hello,
New guy here so I'm not exactly sure how this works...

I am currently building a multiple tank stand (4 - 40 gallon tanks)and plan on using horizontal internal overflows. I'm planning on having the top of the overflow approx. 1" from the top of the aquarium, using a 1.5 bulkhead for my return to my sump. Since I have never done this before I was wondering if anyone had any advice as to where to drill the holes for the bulkheads relative to the top of the overflow (glass tanks)? Is there are ideal amount of drop to have below the water level in the tank? I plan on having approx 500gph going thru the overflow. Any help would be greatly appreciated!

Thanks.
