For all you tank building engineering types....
Picked up a 50gal tank used to upgrade from my 40 breeder. New tank dimensions are 36L X 18W X 18H and is made out of 9mm glass, tank is rimless trimless (no bracing whatsoever). My questions is: Is 9mm glass thick enough to run said tank rimless? I realy like the look of it, and would like to keep it this way. I just resealed the tank and test filled it. So far so good.

Search the web for tank design and "safety factor". I think for most tanks you want a 2 - 3 safety factor but for rimless I've read 7 - 9. This is from memory though.

I love the look of rimless as well, but am afraid of the "what if" factor, like if some one or something bumped it just right you know?? cause I'd love to go rimless, but like said I'm a bit put off by the thought of something going wrong lol

Exactly my problem, I am just looking for someone with the know how to put my mind at ease. 9mm is quite thick for 50G as far as I am aware, most 50s are built outof 6mm glass.

According to this calculator you have a safety factor of around 5
http://www.theaquatools.com/building-your-aquarium For comparison my professionally built custom rimless is 30x24x24 and has 1/2" glass (12mm) which comes in at a safety factor of 5-6. I think you're fine at that thickness. |

Sounds fine to me but I would assume the glass is 10mm and not 9. A good test would be to measure the max deflection of the glass when the tank is full (how much the tank bows) as that's the major design criteria for rimless tanks.
For reference my tank is 54" long and 20" tall and uses 12mm straphire. |

The aquatools calculator assumes rimless though they don't state it, so a safety factor of 5 should be fine. 7 to 9 is overkill. I use 10 mm glass on my rimless 24x24x20 tank. My friend has a rimless that is about 31.5x14x18 and it uses 6 mm glass (though I could not say whether it is tempered or not.

Thanks for the advice guys, I feel much better about it now, and it is 10mm glass, I measured from the sanded edge and it doesnt account for the slight bevel too the glass.
