Are you going to be putting the sump in the stand or in basement/fish room? If you are putting it under the stand I vote no closed loop. My 180 is the same footprint using a 75 gallon sump with a closed loop, I am literally in the middle of plumbing it and am quickly running out of room. It is really turning out to be a royal pain. I am going to have a difficult time expanding at all. IE calcium reactor or dosing pump.
If I were to do it again I would do an external coast to coast overflow, with a remote sump or I would utilize powerheads. Just my two cents.
