how much weight to fall through floor

so i am thinking about bumping up my upgrade plans from a 90 to a 125. i live on the second floor of an apartment. it will be against an interior wall. is this a bad idea. building is fairly new. i would have a sump at least 30 gallons with rock and sand and some extra for good measure. what are the chances of my floor holding a ton over a 18 by 72 inch area. i honestly think its ok, but not an engineer. anyone have a tank on an upper level??? anyone have a confirmed horror story?? i dont see how its that much different then ground level, unless its on concrete. only difference i see is how far it could fall.

 

i have my 46 and the second floor nothing has happened, all though i always worry about when a lot of water gets on the carpet that its going to seep through the carpet and eventually rot the wood or whatever, but its been almost a year and so far so good for me, you might be able to get away with the 125 but thats a lot of weight

 

I have seen one on the second floor without an issue. On an older building for that matter.

You might want to see what you lease says.

 

Make sure the aquarium is allowed in your lease (ask them if a 125 is OK on the second floor, I had to put my 75 on the first floor). If it falls through the cheap freaking floor and they allowed you to put it in there and you had clearance, that's their problem, not yours, and they should pay for the tank. I wouldn't worry about it too much, provided you have permission to put it in your apartment.

 

it all depends on the floor joists. ive got a 90 in my room on 2nd story. when we built our house 1 year ago we went overkill on the floorjoists. my 2nd story floor can literally support a hummer. or an elephant. whatever sounds more awesome sorry i really didnt answer your question, but if the joists are at least 2x6 with 2 ft spacing you will be fine. have you ruled out the possibility of cement? most buildings built these days are mainly cement.

 

yeah ill have to check, good point. not even sure if i am allowed to have the 55 . its technicaly a condo cause its owned, but there is still a HOA kinda thing. so i will check with that

 

There are articles on the net about this...This subject has come up before. I believe there is a standard weight per square foot that has to meet building code.

 

I have my 75 with 30 gallon sump on the 3rd floor.. also all last week it sat next to my 30gal with about 15 sump, next to the TV and entertainment center with the bathtub on the other side of the wall from the 75, taking a bath or two.. I wouldnt worry.. If it breaks, get a good lawyer.. it works

 

bama brings up a good point. put your weight plus the water in a bathtub. the floor can obviously support that. i dont think youll have a problem

 

i just found this....alot of really good information.

however after reading it i am not any better off. maybe even worse off (i hate it when this happens, more info i get the more confused i am)

its kinda tough cause i cant see how the floor joists are laid out. if the wall the aquarium is against is load bearing, not a big deal. however...if its a partiton between the kitchen and the living room i might be in trouble. the tank would be almost in the middle of a large span of joist. assuming the joists run that way.
