Livingroom Floor Joist Strength to Support Aquarium

Postby ramsay » Wed Dec 27, 2017 3:28 pm

Hi
I'm proposing putting an aquarium into my living room. The length of the aquarium is 7ft long x 1.5ft wide. The approximate weight when full of water is around 1000kg.
I have lifted an access panel to have a look under my floor to see what way my floor joists are running. They are running the same direction as the length of the aquarium tank.
Could I have some advice if my floor joists would be strong enough to take the weight ?
In my picture the tank will be sitting over the joist area that's supported by brick.
Thanks
Brian

Id chop up few 4x2s into 1f lenghts,stick them flat on the concrete ( use some damp coarse under them) and then screw in vertical supports running from joist to timber on the concrete. I did that when i got snooker table 7 years ago and so far all good.

extra legs a great idea as above or run opposing direction 6x2 joists underneath chocked up on blocks. This would spread the load really well and give a post and beam type load spreading effect.

I did both of the above when adding a 250kg concrete island in my kitchen last year. It hasn't fallen through yet ;-)
