Sorry I don't know how to work it out, apparently it's about 2.5 tonnes of water.

Would this be totally unsuitable for an appartment ceiling/floor?

Bearing in mind the weight would be spread out across 12 foot. So would be twice as heavy as a 6 by 2.5 by 2.5, but the weight would be spread across much of the room, not sure exactly how big the room is.

My appartment is a converted house, not purpose built. So I think it's just got beams etc.

If worst came to the worst I could always half fill it with water.
 
That's a 560gallon tank that'll weigh in at just under 3 tons once you figure water, gravel, tank, stand, etc. That's 200lbs per square foot. Not bad for a cement foundation. If the floor is raised beams, I'd see about reinforcing the beams with blocks and a couple of cross beams. You don't want to find out the hard way that the floor wasn't strong enough.
 
i dont know the math but the book i have says that length x width x height (in inches) divided by 232 will give you how many gallons the tank is then 1 us gallon = .8 imperial gallons. then 1 imperial gallon = 10 pounds in weight..then add the weight of the tank and stand . as for the structure holding that weight i dont know but i hope this info will help you.
 
wow....i would have never figured all that out, your a hardcore fishkeeper oddball :thumbsup:
 
And everyone in my family thought I became an engineer because I liked heavy industry. Little do they suspect that I studied engineering so I could plan my next tank, in my head, during boring meetings.
 
thanks for the info, it does not come with a stand, and I don't have time to make one if I decide to buy the tank next week, so I would have to put it on the floor :D

To be on the safe side I could fill it 2/3 with water. 130 odd lbs per square foot would be fine surely - even in an old victorian house with beams/floorboards?
 
For future reference, to find gallons, multiply lengthxwidthxheight in inches, then divide by 231.
 
thanks glory.

This is so tough, even though it's completely impractical, it's so tempting. It also comes with 2 4 foot sumps.

But a 12 tank on the floor, I would not even be able to use the sumps. Also would water changes be impossible with a tank on the floor?
 
really? But surely as it's so long the weight is quite dispersed?

Would you still be afraid if it was filled only 2/3?
