How much flow can a 1" bulkhead handle?

This will just be a regular 90 degree elbow overflow, no sipon, gravity fed. How much flow can a standard 1" bulkhead handle. I have read everything from 150 to 700 GPH. I will have 2 bulkheads, one inch each, seperate piping all the way down. I have my eye on a 1200GPH pump. There will be about 4 feet height to push up with 3 90 degree angles and one 45.



Would the 1200GPH pump be too much? What would be the max size I can get that I would not have to dial back a lot, or any.



What I have right now is about 600GPH return and it comes out to a dual return, but seems really weak. I want something that will really push the water and make a difference in flow.



I plan on returning the upcoming setup with 4 outlets, 2 of them possibly with rotating water deflectors going the opposite ways from the middle pushing toward the powerheads on each side.
