You also have to consider that in this case you potentially have 200lbs spread over the weight of one foot giving you aprox 5.5 PSI on 'the magic spot' presumably one floor joist. That's also not accounting for the extra momentum of this persons weight being transfered down. With the tank you would have (aprox) 1600lbs spread over 1728 square inches and at least 3 floor joists... this being about 0.95 PSI. This is a resting weight... no bounce or momentum involved. You'll likely still get some flex, but not the same as a person bouncing along the floor. I personally would not hesitate to put that size of tank in my house, but as everyone has suggested, double check with somebody who knows. Even a good LFS will be able to answer this question properly.

The terminology is live load vs dead load, if you weren't sure

But you are correct, the difference between load types is exponential.

I have 155 main + 33 sum on my main floor. It is perpendicular to the joists and near the outside wall. I did not see any problems for couple months but then i got a contractor to do Joist Sistering to be safe. I probably going to build a support beam underneath once i figure out what i want to do with my basement. Be safe than sorry :-)
