Aqueon megaflow holes

[Alex]

I just bought what I believe to be a 90 gallon aqueon megaflow tank. It seems like both holes in the overflow are 1.75 inches. Could someone confirm this? Wouldn't that be 2 3/4 inch bulkheads? It looks like the plumbing was a 1/2 inch return and a 3/4 inch drain.

Sorry meant 1 inch not 3/4 inch

I have an Aqueon 210 with 2 mega flow weirs. I'm pretty sure the return is 3/4 and the drain is 1.25" reduced to 1"
