Where to put 350 Gallon Tank

[greenlangtern]

Moved back in with my parents and just got a good deal on a 350 gallon 8x2x3. After building a stand and setting up the filtration I planned on setting up the tank in the garage but my father insisted to put it somewhere we could enjoy it better so we moved it to the first floor dining room/family room. However, my grandmother deeply objects to this and says it will be too heavy for the house to hold up and it will cause damage. This house is two story and 6 bed 3 bathroom. It's custom built in 2003 and houses my whole family.
Should I risk damaging the house and setup the tank in the dining room located at the very South end of my house? What are other people's experience with big tanks in the house?

If it is on a slab you're fine. If there is a basement or crawl space you may want to add some braces depending how well the house was built.

This COMPLETELY depends on the floor framing members, which direction they are spanning, and how close to a bearing wall the tank is located. Your tank will weigh 3000 lbs plus when full which is about 125 lbs per square foot assuming an 8 x 3 footprint. Depending on how close to the end of the supporting floor framing members it is placed this could be a big deal, or not a big deal at all. So short answer is - more info is needed.

for every square foot of water it is actually like 86 pounds..

One cubic foot of water is 7.48 gallons. One gallon weighs about 8.35 lbs. 7.48 times 8.35 is 62.458 lbs. Not 86. If the tank is 2 foot tall that's 124.916 lbs. Or pretty close to 125 lbs per square foot.

but the pounds per square foot is only dependent on the square footage that your stand actually makes contact with the floor.

taking the whole footprint of the tank is not correct if it is on a stand with 4 legs, for example.

most stands are perimeter type, so its the total weight divided by the square inches of the area where the stand makes contact with the floor only.

that being said, unless your first floor is concrete, you will need reinforcements for certain.

there aren't many residential wood floors that can handle 3500 pounds of dead weight in a relatively small area for a period of years..

for a tank that size, ground level is best.

I know it may not be the best place to view it, but a 350g tank cannot be put just anywhere. its too heavy when full.

Well the tank I meant to say was 8 ft long by 2 ft wide and height is 3ft. Also I made a quick sketch of my house and how it looks where I'm putting it at.

The second story has 5 bedrooms and 2 bath. 3 bedrooms are at the top of the house and the last two are on the right making a rotated L shape.

Oh woops I forgot to put that the bottom right room in the sketch is the garage and it extends farther out than the front door in the middle bottom. and that room above/below the stairs is a bathroom.

Yeah I believe this too and I forgot to mention my stand is perimeter style with 2 dividers in between the 8 ft distance so its basically 3 cubes put together to make one stand. I put it on a plastic door as well so it can slide on. The flooring is also tile flooring there and the house is built on a crawl space.
