Can my first floor support a 250 gallon tank?

[Trembz]

Hello

I recently purchased a 250 gallon set up from somebody, tank is 60"x36"x27"
Sump is quite small at 35 gallons and I'm not adding any sand to the DT.<br />
I have to place it on my first floor as my basement is unfinished and used primarily for storage and old junk.<br />
I will be placing the tank against the supporting wall held by a beam (the beam is sitting directly on concrete in the basement)<br />
It will be supported by 4 joists at 14" apart and running perpendicular to them. The joists seem extremely thick

I should also mention, I currently have a 150 gallon sitting in the same room that the new tank will be going in. The 150 is sitting on the left wall of where the new tank will be going so it is currently NOT sitting on the supporting wall and is running parallel to the joists rather than perpendicular.

That's a tough question.
250 tank + 35 sump x 8lbs per gallon =2280 lb.
Add to that about 500lb of glass tank and 200lb of rock and about the same in equipment give and tank for a TOTAL of 3180 LB give and take.
It's like parking a HD one ton truck in your room.
IMO I would do some extra support.

Run a few beams under the floor joist where the tanks gonna stand hold em up with some house jacks or 4x4s maybe. It's alot of weight but its spread out over a span so that somewhat helpfull I have a 220 that I framed into my wall and I built the stand out of 2x4s and they're holding the weight just fine.
