I think it's aqueon... I took the sticker off already

Looks like the hole is 1 3/4" so I should be able to get a 1" bulkhead to fit.
Thanks for pointing that out.

Indeed, I understand about the volume in & out.
What I meant to say was, if I was to have decent flow coming out of that many returns, then maybe the volume would be too much for the drain to handle?

How would I go about running it at full siphon?
