Also, my sump is a 90g wide, so it's only 18" tall, which means with a 9" baffle, I have 45g volume filled and 45g to spare.

I feel it's unnecessary to have that much extra room. My current 120 drains like 6 gal when the return is shut off.
I figure this tank will drain 10-12 gal so having 20 for spare is fine for me.
