hole size????

[Vstar99]

Ok well after my takin it slow on my build i am ready to drill some hole in my tanks. Due to design I will attemp to place an internal overflow on the side with only one pipe going down. question is what would be the recommend size should i drill the hole 1"? 2"? I still have not settled on what kind of return pump i will use either.
thanks! - E!

Tank = 55 gallon
Sump tall 30 gallon

i would drill a hole big enough for a 2" bulkhead or two holes each big enough for 1.5" bulkheads.

Hi Ace thanks
so would this be the goal:

3 inch (77 mm) diamond coated holesaw enables the use of our 2 inch 'Whale Passer' bulkheads
