120 on 2nd floor

reefnewbie54321 · 04/03/2006, 08:32 PM

My dad build the house im living in and its only 5 years old, when I asked him what the biggest tank I could put in he said a 100 gallon and a 150 if it was put on a exterior wall. I am setting up a 120 gallon with a 50 gallon sump (placed inside my closet on the opposite sidew of the room)

I trust my dad but I just wanted to double check, hes not to math savy and I dont want to be blamed when the tank goes through the floor lol.

What do you guys think, I heard it was 75 pounds per square foot but my Dad says its more on an exterior wall and he was saying something about the floor joices ect. he seemed to know what he was talking about considering hes a general contractor and designed and built the house himself.

Standard 2 X 8's on 16" centers will hold a 125 with a sump. And yes, against a wall is stronger than in the middle of the room.

The situation is different for almost every application. If you are truly concerned about this you should either post the exact specifications of the flooring, support, construction, etc and maybe someone here will have some answers. Or hire someone to look at it.

eee

I think this is the best article on this subject I have seen. Most of the replies you get to this question will be rather worthless or people guessing. der Riff-Konig - this is not directed at you in any way.

Double check the link anjhof posted, but you should be fine.
If you can, put your tank where it will span several joists, as opposed to in line with one or two.

Spanning several joists is good... I think it is basically the same difference but against a corner of the room is also beneficial.
