I'm geting ready to build a 36x36x36 cube aquArium and I was wondering what glass thickness would be ok...

That really depends on what you consider acceptable safety factors and deflection. I think 12mm (1/2 inch) would be minimum.
3 feet is a very deep tank and IMO you are asking for trouble no matter what thickness you use. I'd very much recommend a welded angle iron rim top and bottom.

Would it just be safer to step it down to a 32x32x32 witch would make it 142 gallons

36" high demands 3/4" IMHO. 1/2" should not exceed 26"

Thanks time to go get glass prices.

Atleast 3/4 inch. I still think a rim should be used, glass and silicone are strong but the weight and pressure could eventually lead to failure. I know all to well. Was once lifting a 3000 glass piece with a crane at work, it was a insulated piece, silicone failed from weight and piece sheared off. Got us scared, which was a good thing because a week later the crane snapped and 6000 lbs fell 3 feet from us where normal we would be standing a week before. Moral of the story, be careful, sometimes things don't work as expected.

36" deep? How long are your arms?

Wow, you were all lucky!

Yep it was me and my 2 friends, very lucky. We were pretty angry about the situation as they used faulty gear knowingly without telling us. Plant got closed down a month later, talk about karma. :thumb:

Sorry dont mean to hijack. Thats a good point, 36 inches deep, might need a scuba mask when your trying to catch a fish!

What type of fish do you plan on housing in this, just out of curiousity?

My 110 is 30" tall. Not sure how thick the glass is, but it's pretty hefty. Probably leaning towards 3/4". And it is VERY hard for me to remove rocks or do much work in the tank. Especially since I am only 5'6".

My 150g is 30" tall and I HATE working on the bottom of the tank. I'm 6'2" and it's a PITA. Last tank I'll ever own that's this deep.

My tank is 70cm deep and is not easy to do stuff at bottom of the tank
