155 gallon bow front

I recently purchased a 155 gallon bow front aquarium it isn't drilled yet but I do want to drill it. I'm just not sure as to how large the holes should be or the bulkhead size.

I
used Glass holes overflow for my 60 gal tank with a 700gph I would think you need a 1500gph overflow .I would check to see what they recommend .

Thanks, I'm still trying to figure everything out up until this point all I had was a 16 gallon nano reef that just crashed
