Also, consider your stand's dimensions. A 30-gallon sump might be tight if you've got a narrow stand. Measure twice, buy once.

True that. My buddy crammed a 40-gallon sump into a stand meant for 30, and now he's got to disassemble half the tank to clean the skimmer. Sketchy vibes.

For anyone on the fence, remember that sump size affects evaporation rates too. Bigger sump means more top-offs, but it's worth it for the stability.
