Got a good deal on a 700G GLASS TANK, BUT WILL IT HOLD? Help please (pics)

Just got a very good deal on a Glass Tank of the following dimensions 10'x3,2'x3,2'

it comes with a large sump, overflows, stand, pump and some other stuff,

the whole thing is gonna cost me less than $1000 so I think its a pretty good deal since I was looking to make large tank by myself at this point.

but my concerns are if its safe considering the volume and height of water, I am considering to modify the overflow in order to keep the water height at about 2,5'.

the tank has a double bottom and some bracing on top, since I'm not familiar with tanks this big, I'm turning to the more experienced guys here to provide their knowledge,

I only took a couple of top pictures of the large tank showing the bracings and also the last pic is from a smaller tank but it shows the way its joined at the bottom

Obviously transferring this will be a killer job.
Thanks guys

No bracing is missing, this is its way of construction, it was emptied a year ago after a year of operation, there were other tanks there also all upwards of 300G and they were all made this way,

Im not familiar with glass ranks this big so I need to know if its gonna be ok on the long run.

thanks for the help

sorry I thought I mentioned the glass,

its 20mm thick

From what I saw, it has a double bottom, the lower sheet of glass is 20mm bigger on all sides than the top sheet, providing more surface joined with silicon, the bottom one and the side one, I think you can see this on the last pic.

I just wanna know how you guys would go for this tank with glass, or maybe there is something I can do to provide some more strength to it

Hi

Until December ´14 I had a glass tank similar to that: 10 x 4 x 28". It was built with 15mm glass and had a safety coefficient/factor of 3.5. Usually companies aim at a minimum safety factor of 2.5. (technically my tank could have been made with 13mm glass)

The company that built it said that if I wanted to go to 30" high and to have the same safety I would need 19mm glass.

I am not an expert in building glass tanks (only in buying them...) but I would be scared with 3,2 high at 20mm = 2.5 safety factor.
I would aim at a minimum of 3.

So, based on this calculator:
http://www.theaquatools.com/building-your-aquarium

with 20mm glass you would be able to have you water level as high as 85cms/33". So, based on that , at 2,5´ I would "feel" safe.

Edit: as long as the silicon is good...

Dear,
thanks for the advice, these tanks are up for sale from a now closed public aquarium, it operated for just over a year,

a friend of mine got a 1200liter tank from there and has been operating it with no problems for about a year and a half now.

anyway Im thinking of modifying the overflow on this tank so that the depth of water will be about 2 feet. This should reduce the pressure on the walls quite a bit I think

was your tank only silicone joined? Or did it have any additional bracing at the bottom?


I just want to know how would others build a tank this size using glass..

And.. What happened to your tank??
