One of those holes is for the return. Are you planing on using all three holes for the drain? Check out the sticky's in this section and they tell you how much a 1" line will drain. Double or triple that amount and you will be set. Depending if your using all three as a drain or just the two.
Alot will depend on how you want to plumb your drains. With three holes you could run a Bean and run your returns up and over the back, or you could run Herbie style and run your return back up through the overflow. Either way, you'll be running one full siphon drain which can handle alot more flow than a line mixed with air.
On my 300, I run a pair of Quiet one 6000's moving about 1200 gph each at 6' head. My drains are dual herbies, but I'm using 1 1/2" drains. These are mostly overkill for my current setup, but I could eventually see upgrading my pumps and or turning it into a reef tank, so i built it for the future.

ok im new to over flows and sump so bear with me if i asking stupid qustions but why would you want a retern come up in the over flow and then in the tank? would'nt the filterd water just run back in the over flow? and from what i have read so far a 1 inch hole will drain close to 1000gph right? so thats 3000gph if i use all three is that to much to run all throw the wet dry? also its only has one over flow is it even possible toget that much gph with one over flow?
If you used all three holes for drains, you could plumb your returns to come up and over the back wall of the tank. If you used two, you could run your return back up through the overflow and into your tank, or you could go up and over the wall like the first example. The second way, coming back up through the overflow essentially eliminates and plumbing behind the tank or in the field.
My 300 in my sig is plumbed with both drains and returns running through the overflow.
1000 gph sounds about right, but depending on how you plumb your tank, you're going to want to use at least one line as a dedicated emergency drain for safety purposes.

ok so if i use two of the hole that gives me about a 6.5 turnover and all three would give me a 10 turnover. im keeping pacu flowerhorn jaguer and planning a ray not sure what kind tho. im guessing i need close to the ten mark to keeep the ray happy how will the flowerhorn and jag handel that?
Here’s the wrinkle in your system. The over flow area in your tank was designed with 3 holes. Two are meant for drains and one is meant for a return. If you use all three as a drain and go for 10X turnover rate the actual over flow (the thing with the combs on the top) will not be able to handle the water and your tank will over flow and spill to the ground. To get past this you need to somehow lower the overflow or cut some of the combs off to make more room for water to spill over the top
ok but i think it was set up with all three as drains cuz ther are three more hole in the bottom of the tank but i plug them cuz i did not want the returns to in the middle of the tank. so i think this is what i will do use two as drains and plug the other. the returns will run up and in the tank on the back. sound like it will work?
