65 gal on 2nd floor question

[Aquattro]

It's fine

Maybe put it near a supporting wall? That's what I did with my large tanks on the 2nd floor

I had a 60g on the top floor for over a year with no problems.

Lorenzo The tank is running north to south along with my joists.

Aquattro - so if I'm only on 1 joist am I still ok ? WHat is usually the weight 1 joist can support in a 36" area ?

[Aquattro]

Well, it isn't just one joist, as the plywood spreads over several and distributes the weight. If you can jump up and down on one spot and not go through the floor, it's fine. The weight/sq. ft. is not really all that much. If the place is really old and shaky, you might get some wobble in the whole display, but it won't go through the floor.

with a 65 g tank you should be fine. How old is the house? The I-joists used in newer homes would have no probs with the weight.

[Aquattro]

Realistically, the tank is what, 4sq.ft.? So at 800# at most, that's 200psf. If a person of 200# can stand on the floor in an area of 1sf and not go through the floor, the tank is fine. If not, I'm not coming to your tank warming party

FWIW I have a 90 plus my RO res at 45gal sump miss tank all on the top floor. You should be fine.

[new but handy]

my 180 plus my 55g sump are on the second floor of my house. no problem with yours. If you are still worried, exterior walls and the walls around your stairs are gauranteed bearing walls. Most walls in your house are not bearing. 2x10 floors are stronger than TJI's. If your tank is 36x18 you are pretty much gauranteed to hit at least 2 joists. Most joists are on 16" centers. Aquattro is right about everything, plywood spreads the weight more than you would believe. I weigh 240#(don't tell anyone) I would noy hesitate to pick up my 120# girlfriend, my 40# kid and my 90# dog. I would stand on 1 foot for about 1500#'s per square foot. no problem

Absolutely no worries at all! How buot a jacuzzi tub on the top floor?
