If you don't use a drip plate I feel you could use the 12x12 area with some egg crate on top with some sponge that should be able to equal out the flow? I don't have any experience with that much flow. If you double the bio area, that will increase the contact time with the media as well with such a high flow rate.
But it also cuts my sump area for extra water due to power outage. I was going to use a 75gal and I wasnt going to have to make it work...but now I dont have the room for one. I dont know the hole size or spacing...but if I had to guess id say holes are maybe 1/4" and probably 1" apart. I know you got a formula for that lol
