Pull the carpet up and see what u got.

I believe I may have to do that. If they are perpendicular, How big could I go safely?

That I can not answer, But is should help you determine what the floor may hold up.

What type of floor are you placing it on? Carpet? tile?

Edit: I personally would not hesitate to set that tank on that floor system as long as it did not violate property rules. What kind of stand is it ?

Edit: Most engineered floor systems have a safety factor of 3 so it would probably actually hold 360 psf.

Edit: Even if the joist run parallel the load is distributed to the outside band/wall, the joist under the tank and at least the next joist for a total of three. If the joist are running perpendicular then it is only three joist in the 48" of tank

Excellent. It would be on Carpet. Grouper, PM inbound.

4*2=8
8x120=960
960 = 300# for cabinet/stand/equipment/rock/etc + 77 gallons of water..

so 75 gals or less.. (my recommendation - even though the footprint will be smaller than the 4'X2' used for a calculation, the overall weight is much less..)

I can tell you that a an adult in a garden tub probably blows that equation apart especially if you consider how much of the tub actually contacts the floor system.

yes, but tubs are planned for...

an aquarium isn't..



(never seen a tub on an upper floor that didn't have double joists under it.)

If I remember correctly most residential floors were designed to carry a a live load of 40lbs psf but that is for the entire room. for example a 10'x12' room would be 120x40=4800 with a safety factor or 1.5 gives you a live load of 7200 lbs distributed over the entire floor.
Obviously the closer to the end of the joist the greater the load can be per individual square foot. Most of the houses I rammed in the last 20 years would carry the load of a 120 AFTER THAT I WOULD DO SOME MORE INVESTIGATING AND RESEARCH .
Glen at Spike corals has years of experience with residential construction as well.

most of the time

The span (unsupported length) of the joist matters also. I had once found a website with the LB capacity of most dimensional lumber, but I can't find it now.
