Thing is , you NEED to make sure the span is across the joists not running with them. Generally, speaking joists run from front to back, on a house with two stories you can ussually tell by wall placement.
Having the tank setup along an outside (or load bearing) wall is a much better location than along the middle of a floor span or non-load bearing wall. It doesn't matter if the home has 2x10 or 2x12 as much as how the floor was designed. A 2x10 floor joist under a 20' wide house with a center beam may flex less and be much stronger than a 2x12 that has a longer span section. Most homes that use 2x12 joists instead of 2x10 joist is because they are being used to span longer sections, hence the need for a larger joist. I've seen a couple different floors bow due to people setting up large tanks over too weak of floors, to the point that people added large amount of shims to level a tank even though the tank started off level. Will the weight of the tank bring the floor down, probably not. Can it make the floor deform and crack drywall on a finished off ceiling under the tank, yes. I'd rather be safe than deal with trying to fix a floor.

i've had a 200 gallon system in a 2nd floor apartment for 2 years with no trouble. wooden flooring as well.
All floors, and homes, are not created equal. Codes for apartment building very often exceed single or double family homes.
