Will my tank end up in the basement?

I am putting a 120g tank with 250lbs of LS and 120 lbs of LR on the second floor. It will sit on two beams with the beams running from side to side.
Does anyone really think this will be a problem?

It is a regular rectangular tank. 48 long, 24 deep.
I will also have a sump underneath.
What do you think? It is new construction and the guy told me that a water bed would be fine, but they are larger and more spread out obviously.

well is the tank going against a wall? if so what is underneith that wall on the first floor? if there is another wall just like it on the first floor then it is prob a load bearing wall and you might be ok if there is open space under the wall on the first floor then that would mean there prob is not any 2 x10 or 2 x 12's under it and i would def not try it, if the builder is around your best bet would be to have him stop by and ask him he will know what is under the area you wish to put the tank and should be able to tell u if it is safe or not to put 250lr 150ls 800h20 glass tank 125 total approx 1500 lbs

I though about the weight of my 90g tank being a problem too. So this is what I did. I went and bought 2 8ft long 2x10's and cut them in half. Then I nailed the 2 halfs together to make a 4ft long piece. Then you can use a couple 2x4's or whatever to prop them up undernieth the beams the tank will sit on. Make sure if you use 2x4's to double them up to make them stong enough. IMO it's better to be safe than sorry. 1200 to 1500 lbs is a lot of weight to add onto ANY floor.

Ok here is what I found out. I talked to a builder and he said that any floor is made to handle 200lbs per sqf. He said that my tank will be no problem at all. It is 4 feet by 2 feet for a total of 8 square feet. 8 sqf at 200lbs is 1600 lbs with no problem.
Here's an interesting point he made, he said your foot doesn't take up a whole sqf, so stand on it and see what happens. That means that if I stand on one foot (I weigh 200lbs) I am fine.
He seemed pretty sure of himself. What do you all think?

With rock, sand, etc and weight of the tank and stand, you are looking at 10 - 12 pounds per gallon.

Good point. The sand and rock will actualy displace a few of the water gallons so it is not truly 120 X 9lbs.
So useing the 12lbs per gallon for water, sand and rock I am at 1440lbs.
The tank stand and cap weigh how much? Maybe 250lbs?

Ok you said your tank is going on the second floor right?
So your bedroom is on the thrid floor.
Do you have a basement? If so I don't understand why you cant add support to the floor. I'm sure you have a way to get under the floor because you said it will be sitting on 2 beams that run side to side. How would you know if you didn't look under the floor?

2nd floor is really upstairs. The first floor is the main level and then there is a basement.
I am assuming that the beams run that way becasue when you go into the basement you can see that they run that way on the 1st level.

If that were an option why would I have even brought this up?
Anyway thanks for all the advice we will see what happens.

O ne way to spread the weight out is to put a piece of 1-1/4" subfloor under your stand. Then for every inch you extend front or back you add 48 square inches to the equasion plus you can insure that there are 2 or 3 floor joists bridging your tank. This also flattens the carpet out more uniformly and makes repair and clean up easier if you move.

Efrank ok you really need to listen to me.
Go down into the basement and add support to the floor that is above your head. From what you have told us there is NO reason you can't add support to the floor. It's totally up to you but I wouldn't take the chance of f***ing up my floor.
