you should have an engineer come and take a look. The fact that the house is new doesn't really matter if the house wasn't built to support the weight.

Yea that's not a bad idea gotta look into that anyone here on MR an engineer lol

I would say Yes unless you have concrete floors. Residential floors were not designed to hold up 3000 + lbs in a 18 square feet area.

+1...when I put a 300g (8'x30")in my living room, years ago, I had an engineer look at the floor joists, and he suggested sistering (doubling) them up!, because they ran length-wise with the tank.

I'd be more worried with your tank/setup, because of the dimensions, that would put even more weight on each joist. You're probably talking about closer to 5000 lbs. in 18 sq. ft.

Yea thanks guys im def gonna get an engineer

Check out my build thread I have a 300 on the second floor and I braced my floor and also sister the joist

 

[mazon56]

Thanks armani I checked it out that would be the ideal thong to do but my basement is dully finished with tile and I have a game room set up down there I would have to really look at it and brainstorm. Now if I we're to get a 220 would I still require to reinforce the floors

I would either get an engineer in or get someone who can sister the joists for you in either case. Like Albano said, it also depends on which way the tank sits on the joists. If it's perpendicular odds are you will be ok with the 220 but if they run parallel you might want to reinforce them. You should also err on the side of caution in these situations because it's easier to sister joists than involuntarily relocate a 300gal to the basement.

I'm sure he meant 'unavoidably downstairs'.....as in a catastrophic failure....flood

Russ would be correct.

The dynamics of the whole room would make a difference! Depending on which way the joists run and the over-all length of the actual beams and the actual material used to build the floor. If it is newer construction they may have used engineered lumber (the i-beam looking joists).

When I did my addition on my house I have my family room that is 17 X 27, so in the area where the new bathroom was going to be above we actually had the 2X12's on 12 in centers vs 16 centers. And that is only for a bathroom without really sustained weight.

I think that I would definitely support that amount of weight. In the basement. If the joists are running perpendicular to the length of the tank, then a support that is parallel to the tank underneath. If they are running parallel to the tank then that is a different story since you want to make sure that you have full support especially around the edges of the tank.

When I built my home, I planned for a future wood burning stove on the second floor. I reinforced the 2 x 12 floor beams by building that section of the 2x12's as 8" oc.

thirty5 laid it out very nicely.
