Max wieght on a floor

this might be a dumb question, but here it goes anyways. I recently bought a 3 floor town house and I have always had my tanks in the basement or on the ground floor so it was always concrete under the flooring. In my new place my office is on the top floor and I wanted to set up a 60 gallon tank a 29 gallon and 2 20 gallons up in my office. so the bottom line here is should I worry about the floor being able to hold that much wieght? I'm lookin at about 129 gallons of water. So thats roughly 1290 pounds. If that is to much does anyone know how to figure out how much Is the limit? Thanks all!!!

i honestly dont know but you brought up a really good topic i never thought of something like that hope u get an answer so i can see the results too

all I know is my dad tried to put a 210 in our living room one time and it went right threw the floor. it was an old house thou and this is new construction.

There should be a city code that specifies the amount of weight a floor can take. You may need to work it out in pounds per square foot, but somewhere in the architect's drawings and the construction permit, a number should be specified. On the other hand, if you put a heavy aquarium next to a load bearing wall (right up against it) the moment arm will be short, and the wall should hold quite a bit of weight. Before you put the aquarium in the middle of the floor, check the local construction codes and building permit. To avoid stressing the aquarium, you may need to put shims under the stand and check for level every now and then.

never thought about the city codes!! the tanks are all going to be against the wall. I would imagine I would be ok but I will see if i can find anything in the codes and permits.

On sky scrappers I don't think there's any problem - it's made of concerete and steel.
My aquarium is probably around 1200-1400 pounds and it's sitting right in my living room.
I placed it near a main construction setting, just in case.
If you have a larger tank, I'd consider bringing an expert to the place, to check it out.

thanks all for the help

Most of the older houses in sunny Phoenix are built on cement slabs, so weight bearing ability is not much of an issue. However, settling is, as some of us cracked aquarium people will attest.

My husband and I have debated this hotly. As far as how much weight is too much weight.

As of now, all my aquariums are around the walls. Some with and some across the floor trusses.

My husband insists that going across the trusses is stronger, and more weight bearing than if you go with the trusses.

That being said, he's still wanting to put 4 more concrete and block piers under the floor in the fish room...

One more thing holding me back from the fish room... BLAH!!!

The extra piers would probably be a good idea. Can you imagine what would happen if the floor caved in? In northern California earth quake territory, they use steel beams rather than wood as floor joists.

I would not want the floor to cave in...

But I want my fish room!!!
