Unfortunately, I'm probably restricted to one overflow , so for 150 gallon aquariums it's advisable for a 1.25" bulkhead/drain pipe and go for a 1 inch return/bulkhead ... or go for the slightly smaller combo of 1" bulkhead/drain and 3/4" return/bulkhead

Hope my last post was not to hard to read. The quote never worked proper for some reason. A single is fine then. You could use the sq. one as I mentioned or the angled corner type someone else mentioned. I have pics of both types if you wish to see them. My preference still would be whatever size hole it takes for a 1.5in drain but if not possible then a 1.25in. drain.
