Weight of a 300 gallon

[Dan F]

A 24' x 96" 300 gallon sits on about 16 square feet of floor space, maybe 180 lbs. per square foot. As long as your apartment building was built to code in the last 30 years you should be fine. If you have the option to set up the tank perpendicular to the floor joists, do it. I have a 300 gallon acrylic set up at our school. It is on the second floor (there is a basement under it). Anyways, our school was built in the '40s and the floor seems to be holding it up.

Flame me if it ends up in your downstairs neighbor's apartment, but I would do it!

Ive always been told that water weighs about 12 pounds per gallon on it own plus the tank ,substrate,stand, plus monster fish

Water weighs 8.33 pounds per gallon.

By the way, the "pounds per square inch" hypothesis is a dangerous oversimplification of the issue. I suggest you have a structural engineer run the numbers for you in your specific circumstance.

WELL my tank is 350g and its on the 1st floor floor boads

get an acrylic tank it will save a lot of weight on the over tank weight and it will be alot easyer to get the tank in the house

Remember, all that weight will probably not be supported on a footprint the size of the stand. My 300gal stand has 6 circular pegs it sits on, and that's it.

180 gallon on 3rd floor is that ok?

How do you intend to get the tank up to your floor in the first place? If you have to go around stairs, you will have nightmare.

For an apartment why take big chances, get a smaller tank for now and you will have to look forward to a big tank in your future in a house.

if that is the case, what in you guys opinion is a good size for a 2nd floor, wood floor......Is 180 okay, if thats the case, would a 240 be alright because it's extra two feet would be spread over more joists?

300 Gallons [US] = 2,503.5792328 Pounds is the actual weight of JUST THE WATER in your 300gal tank.
I would say that 1.25 tons on a second floor apartment dwelling may eventually lead to structural problems. If your apartment complex is relatively new and created with engineered trusse...... Let me say this, if you want to set up a tank that big, move to the ground level. If you set it up on the second floor, one month, one year later, the weight of the tank (with water) may cause the gusset plates to shift (in the trusse). This could lead to saggin in the floor(landlord would take you to the cleaners) or it could cause your 300gallons to cause undo & uneven stress upon the tank itself. This would end with the contents of your tank no longer in your tank. Again leading to LandLord troubles.
