440 Acrylic tank, what should be the thinkness of the panels?

[plc001]

We have an opportunity to work on a project for a local public aquarium. They received a donated 440g tank that is 96 x 36 x 30 but the acrylic is only 11/16". I'm afraid that the tank may not hold, is that thickness normal for large tanks?

the height is the important dimension, my 96 x 24 x 30 is 3/4" acrylic but I've seen the same tank with 1/2" too, so 11/16 should be fine

It all depends on the bracing on top...but if you are braced heavily you should be ok....

my 375 thats 72x48x25 is 1" all the way around just my 2 cents

Cyro's acrylic thickness calculator suggests an inch thick for a tank this size. It does seem a little conservative to me.

The material on the tank is 3/4", well the metric "equivalent" anyway - 18mm which is .708", just a tad above 11/16". With the exception of one domestic mfr (Polycast), whenever you ask your acrylic distributor for 3/4", you are gonna get 18mm.
Yes, you'd like to see thicker but that is the "industrial standard" for this size aquarium. As stated earlier, if properly - should be okay.

Thanks,

The tank also had some tiny fractures on the joints. We decided that we will not set that tank up. Thanks for the advice.

I rather be safe than have that tank kill some one
