Yup
The math checks out wink
4 cases of 6 gallons stacked in corner,
like an extra person in the room (or hiding in a closet)


1 rooms 24 gallons
2 rooms 48 gallons
3 rooms 72 gallons

This is very conservative way to add weight to apartments
given the internet wisdom
"Aquariums up to 55 gallons can be placed almost anywhere without much worry at all."
