WANT MY TANK BACK

[Sprucegruve]

I had about 390 gallons worth of tanks spread around a 12X10 room and I broke a floor joist.
They were reinforced with 2X4's doing X's between the joists

Be careful,I wasn't,now my fish room is in the basement on a concrete slab

I had a 100g Reef tank on 2nd floor. I think a 125 could safely be kept. I would try to determine which direction your floor joist go. And place the tank so it goes across the joist so a 6 foot tank can lay over 3-4 joist assuming your floor joist 16" OC.

Remember when everyone had waterbeds? How many gallons is that?

This really depends on your place and its floors. No one canl give you a meaningful answer over the net.

There is a fair amount of potential complexity in your question.
For example, below is a link to a professional builders load calculator.

http://www.awc.org/calculators/span/reversecalc/reversecalc.asp

The calculator is designed to be used by builder, but it does a nice job of showing just how many variables are involved.
I'm trying to find something more useful, but that's all I could find so far.

That's a great analogy for two reasons:
1) It's an example of how much weight a floor can hold in relation to the items footprint;
2) When buying renter's insurance you usually have to buy a rider to cover a waterbed because of the potential damage.

Maybe somebody can find a waterbed/weight/floor calculator and the OP can work back from that?

We have a 220g in our 3rd floor apartment. We've had it up and running for about 8 months now without any issues but to be honest I still am not totally confortable about it. I used the dimensions in an aquaruin calculator and figured that with water, glass, filter, rocks, sand and fish the weight has got to be around 2200lbs! We put it where the concrete supporting firewall is between our apt and the next assuming that would be the strongest place structurally and it is still as level on all sides as the day we filled it so the floor isn't bowing or sinking...that said when we said we had fish, I'm sure the rental company never imagined we had a tank like this. People that aren't really into fish, especially cichlids and other serious fish, think a 55 is big lol.
When I tell people my dream tank I want to build soon is at least 300gal they are in shock...then when I tell them that's a baby tank compared to what some of you people have they are in awe...
Anyways, I'd say you'd be safe with a 150 in your apartment...just get the extra insurance in the lease agreement like we did so if **** happens at least it's covered lol.
