Making Cube out of 2 x 33G?

[Delphinus]

I missed that thread Drew, sorry, I was camping the last couple weeks.

Place I use for glass is called Glass Guild. They're up in the N.E. by the .. um .. I think it's the Port-O-Call hotel. Number escapes me offhand but you can call 411 or check yellowpages.ca or something. I find they're reasonable for prices, and, they have everything under the sun - clear float, smoked, tinted, Starphire/low-iron, etc. etc.

Agreed with sphelps - I'd put a Eurobrace on the tank.

Hope this helps!

drew You are going from glass rated for 33 g to putting it on 100 g, I have not seen an eighty + g tank that had less than 1/2 " glass and you want to try close to 100g with 1/4". Dont add salt when testing(save you a little $) and test it on your porch (you can tell the neighbors below you were just putting out a fire) LOL. Now on the other hand if you still itching to try I have a bottom, front and a side of a 33g you can have.

Hey--I know what you're saying. Those were my exact concerns! But I was also told by a tank builder that, as long as you keep the tank 18" and shorter, 1/4" glass will suffice (garf.org also agrees).

Does this make sense to anyone else?

Are there any 36" cubes at any of your LFS's right now? If so, take a tape measure and see what they are made of.

If you keep the tank below 20" tall and do not increase the the length (36") your tank will be fine provided you brace it.

Actual volume has nothing to do with glass thickness, only height increases pressure (m*g*h), however the hydrostatic force created by this pressure will create a bending moment (deflection) and the longer the tank the larger the bending moment, but 36" is fine for 6mm.

No point going overkill on glass thickness, you just loose clarity and add weight.

couldn't have said it better myself

Cool. Thanks guys. I've separated the two tanks (not a positive experience!), and now I have the fun job of stripping all the old silicone off of it. Let's see if I can actually make this work!
