will it come crashing down?

  • We are currently upgrading MFK. thanks! -neo
this makes it a bit tougher but iam renting haha so what ever i do must be easily removed when i leave

You think your land lord would complain about an extra board running along the floor? I'm just asking some people don't mind small renovations that do more than add cosmetic looks lol.
 
What kind of support do you have in the house? I know concrete exterior walls but is there an I beam or girder down the middle of the house? Will the tank be situated parallel to the joists or across them? Across is much better of course, spreading the weight over more boards.

Your stand should be designed to have as large a footprint as possible, also to spread out the weight. What I mean is more square inches contacting the floor distributes the weight better.
 
the tank will be 6x4 running 6' parallel with the floor joists my floor joists are 16" on center they are 2x10 joists and in this specific area run 14' from the load bearing wall to the opening of a set of stairs to my basement witch is 1-2' after a steel I-beam that runs perpendicular to the joists

Hello; A few thoughts on this. First, the long length of the tank running parallel is the weaker of the possible ways to do it. Having the six foot length run perpendicular to the floor joists would spread the weight over more joists.

The floor joists span 14 feet and will support the least load at 7 feet. Having the tank further from the center and closest to either end would likely be best. I placed a 55 gallon tank over floor joists in parallel at the center of a joist span. I noticed the tank water reacting when I walked near the tank due to flexing of the joist. I braced the joists a bit to cure this. Not likely a 55 gallon would have done structural damage, but you are thinking of a much larger tank.

My initial thinking is that you are about to take a considerable risk. Were it your house, that would be your risk alone. As a renter you may seriously damage some else's property. My guess is that you will be liable for such damage. I would suggest three things. First get some renters insurance being sure it will cover that kind of structural damage (And water damage.) Next try to find out what repairing structural floor damage might cost you. It will likely be much more than you can imagine. Last, talk to the landlord. Get an OK or do not do it.

I rented for many years. i worked with various landlords.

Good luck
 
i know having it 6' perpendicular to the joists is a better idea but sadly there is no where i could possibly put it where it runs like that,

id like to have the tank in the corner where the 2 cement load bearing walls meet (the outer walls of my house) oppose to the opposite corner of the room where only the one load bearing wall sits parallel to the tank.

not too sure how i would bring up that id like to place a 400 gal aquarium weighing 4000lbs+ on the 2nd floor to my landlord to a non fish keeper that sounds CRAZY :nilly:
