will 220 gallon crash or bent my living room?

[kevincao]

hi, well i have asked few people regarding to this question, even the carpenters, but i am still not quite sure, it would be best if someone who has a 220 - 250 gallon in their living room to tell me that is fine, and won't bend the house and then goes down to the basement next morning, i'd be in sooo much relief! so please if anyone is currently housing 220 - 250 gallon in their living room or upstairs not in the basement to tell me that it is fine, then i'd be stress free! thanks !

It will bend ur floor if ur not on conrete. My 180 I had in my parents house sagged the floor 1/8". Youll need to support the floor.

You need to make sure that it is sitting perpendicular to your floor joists. Then it may work, for sure it will not work if sitting parallel to the floor joists. Can you get below to reinforce the floor at all?

oh man, where did you put your 180? i am planning to put behind the fridge and beside a concrete wall, so it gets more support, but still not so sure yet. but this seems that i'd be going to home depot soon

yeah i could get down, and it not parallel i just went downstair and checked, also these joists are linked in to the concrete wall, should be fine?

How far do the floor joists span before hitting foundation or support beam? What is the dimensions of your 220g? What is the distance between floor joists on center?

I had a 150 on a crappy 75 year old house with wood floors, I made sure to span the floor joist and had no problem. Even with a 1000 lbs of fishing buddies looking at it standing right in front...
Right now I have a 225 setting on a metal stand with all the weight concentrated on 36 sq inches, (4 - 3"x3" metal pads).
If you are unsure then double the floor joists with 2" x 6"s and support them with pier blocks and 4x4 risers...you'll get a tad of flex but that is the floor system working. Without knowing exactly what you have it is hard to tell ya...If the house is of current building practices then you'll be fine.

Figure out the total weight of the tank and goodies, and divide the weight with the actual area that touches the floor. This will give you a "PSI" pound per square inch figure and you'll see it isn't as drastic as it may seem.

If all else fails put it in the basement to start...

1/8"!!?! how can you tell the floor even moved that much?, Hell, I flex a wood joist floor 1/8" when I walk on them...

the joist is 7dept x 2in wide, didn't measure how long, and it is 16 inch apart from each other, house is 30 yrs old so the wood is better then the new house wood material which was said to be "ecological" the fish tank is 72 x 24 x 30 with an 80 gallon sump but max water for sump ain't much, and total of 253 gallon of water. the weight is 20 psf, standard house is 100 psf, min house must have 40 psf (by law) but of course if i was to put 40 psf of pressure all over the house then it would collapse, that's why i decided to put behind the fridge since it holds more weight, and is right beside the center metal pole thing. so i'm not sure if it'll still bend it

The 180 was on the outside wall with the joists sitting on the foundation

Would the 220 be fine on a load bearing wall yes, but imo your gonna need to support the front joists to stop the floor from leaning down.

Sister joist comes to mind, and just span that to the next support, prob a metal beam.

thanks for the info, i acutally calculate by psf (per foot) umm i've posted the info just above so hopefully it would help you out in figuring out if is ok, and the tank is 0.8 - 1.1 ton after water and stuff
