Im sorry but thats just ridiculus. What did you do fill it with mercury? Never in a million years would 4 structurally sound I beams sag with the weight of a 75 gallon on them. one I beam would have no problem at all supporting 600lbs let alone 4! This is nothing more than an attempt to discourage and sound knowledgeable.
In all honesty I have no idea if it will work...but then again I have never seen the building. It is ignorant to make a claim about something inwhich you have no information. I would say:
1. Talk to your landlord because they may have some problems with a DIY 450 gallon tub of water and fish sitting inside their life long investment.
2. Talk to someone who actually knows about the construction of buildings and the weights they can support.
3. Ask yourself "Can I sleep at night knowing theres an active bomb sitting in my living room that could potentially destroy everything in its path?"
If you can cover all that then more power to ya
Good Luck
P.S. Zdoo, dont let 3 obese people sit on your couch or they will take the express elevator to the first floor. *Sarcasm*
P.S.2 Theres a sticky in the set up and filtration section that details a guys 800 gallon tank + 200 gallon sump...its on the 17th floor. He must have I beams made out of kryptonite right?

no seriously it did, it clearly sank, one beam is rated at 1 ton in the middle never mind at the end. it should have been the strongest place in the house other than the basement, the only theory i can think of why it sank was that either the plywood under it settled a bit or water somehow seeped in and weakened the floor even though there are no signs of water damage, or a combination of both
i wasnt trying to discoruage anyone, just make sure you know what your doing and dont under build the support
to have it all glass with no framing in a 450 is impossible as there is no sealent strong enough. if you were to use an alluminium frame then it would be possible

Points of order...
It's not a bomb...it's a [SIZE=-1]tsunami.
Kryptonite doesn't have physical strength.

Wrong.
Otherwise bichir_first, consider Fish Eat Fish's suggestions and seek some proffesional help.

I know ur pain man. I have a 310 gal DIY its been up and running for a while now in my current home which has concrete slab floors. Now I have to move, its so hard to find a new place with the bottleneck of know it can only be a concrete slab floor...

yes i mean there is no way to have a 450 odd tank that can be garunteed to work with with an amount of silcone that is sensible(ie: looks neat and tidy).so you telling me your 500 has nothing on the corners? or edges? i doubt it. i bleive that soem frmaing is required. as no sealent will hold 2000kg pressure or 4000lbs(weight of a sedan) by itself let alone the glass weight
let me give you some rough insight:
1. tank could weigh up to 500 lbs or more if it's all glass
2. water is the heaviest thing in this situation [8.345 lbs per gallon] [i.e. 450 gallons of water weighs over 3750 lbs]
3. unless you have concrete floors on the second floor, it's either solid wood joists or composite joist system
a. solid wood joists are easy to add modifications to to make them hold more weight + they already will be stronger in rotation if blocked properly
b. composite joist systems are more efficient but allow more bending. large amounts of weight in small areas [i.e. fish tank] will tend to cause more bending in these systems
4. if you are renting... don't bother. you won't be living there forever so moving the tank later will be a bigger chore than setting up your current situation to prevent a structural disaster
i may be wrong as i have not done structural calculations recently, but i believe most floor framing has to meet a minimum of about 15 psf dead load + 40 psf live load. most floors are framed with members that exceed this [unless a builder is trying to cut costs] and will probably allow for 75 psf to 100 psf depending on framing members. If you had a 450 gallon tank that weighed about 4500 lbs with glass + water + soil + stand and it covered a floor area of 24 sq ft [assuming 8 feet long and 3 feet wide] you will end up with 187.5 psf. the main idea here is to distribute the weight over as much floor area as possible so that more structural members are helping support the load.
