I have been given a 225 gallon aquarium and I would like to set it up in my (rental) house. I figure it will weigh about 300 pounds per square foot with a 10 square foot base. Anyone care to speculate on how much weight a floor in a house with a crawl space, not a concrete slab, might hold?

If your house is made of bearing walls and if you put your aquarium next to one of those of those bearing walls you should not have any problem.

Since you have access under the floor you could easily ( edit add obvious missing word) increase the local capacity under the aquarium with a prop or two in the crawl space.

The footprint of the tank is about one square meter, so that would be 1360.7 Kilograms per square meter. 225 gallons = 851.7 liters...The weight of the tank and sand and the stand have to be figured in a well.

I agree with Studiot and Acme, Moon. 2x4 braces on a broader plywood base, up against the joists will support that floor in a crawlspace. I did that under one level in my house where the flooring had some give to it.
