new tank!! 250G DD

[e46er]

I think I will make my sump baffles 15" tall which is 56 gal total volume leaving me 19 gal of room for overflow volume which I think is plenty.

every inch of height in the DT tank is 9 1/4 gal so if DT height drops an inch and the overflow drains down to the fully submerged drain like 6-8" down it leaves me some room for play but maximizes my total water volume.
does anyone see any issues with my calculations?

Baffles that tall will mean your skimmer will not be working at optimum since most skimmers do best in 8" to 10" of water. You could build a stand for the skimmer but that just seems an unnecessary complication.

I've Always had a stand for my skimmer. I just cut 6 pieces of PVC and a sheet of eggcrate
I think it's pointless to have a large sump to only fill it with 8" of water. That's only like 30 gal.

All that sounds fine, and the math is good. Looking forward to pics.

I'm the opposite. I like having extra unused volume in my sump to catch water from the display in case of power outage. But then again, my return is drilled several inches down and so quite a large volume drains from the display. Knowing I have excess capacity in the sump helps me sleep better. 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.

heres some pics. the stand will have doors on in front on the sump with 2x4 bracing between the doors and the right side will have doors to access the controller and electronics which will be partitioned off from the sump, which will have bracing as well.

Congrats . Set up is looking great.
Are you planning on adding a 2 X 4 to the inside of the stands legs, for greater support of the aquarium weight?
