Large aquarium dead load on floor

atljar

Thanks for all the suggestions and help! Ive decided to leave things be the way I have them, but I also stepped down a little in tank size to a 75 gallon which lessens the weight a fair amount.

Ill post a few pics once done!

at 160# per SqFt load, you don't need to do anything on a normal house floor.

If I were you, I would basically build a pier system underneath the loaded area of the floor. I would also connect the floor joists to the wall studs laterally.

Basically a laced post box system composed of 4 4x4s laced together has a safety factor of 32,000lbs. This would be more than adequate. This resists all 3 dimensions of load, as well as racking & twisting.

Or if you're feeling cheap, just use some diagonal bracing into the wall studs for added support.

EDIT: I see you changed your mind. Good luck with the tank !

I have my 55 gallon in the BASEMENT

Agree. People stick over 1000# of full refrigerator on their kitchen floor and think nothing of it. I used to have a 2200# waterbed on 2 x 8 x14', 16" center floor joists. Had that up there for 15 years and never as much as a hairline crack in the plaster/lath cieling. Bed covered 6 floor joists.

What house is designed with a 160# uniform live load?
