Glass Thickness

I am torn between an Evolve 8 and a 10 gallon tank.

Really.

I love the Evolve 8 design which to my mind is near perfect, but I have been told it is not 8 gallons. In fact, the display area is only 4.9 gallons.

So I went to check out a 10 gallon. But the thickness of the glass is 1/8th in. I intend to put heavy sand only substrate in the tank. Yet, most stands have no bottom, but only the glass holding the weight.

I am an engineer. That makes no sense. I can do pressure equations; and a flat surface holding weight is NOT GOOD.

Don't tell me only the edges support the weight. The flat bottom also has to hold that pressure.

1) Is 1/8th" good for a 10 gallon tank with 2" inches of sand and some slate?

2) If I find a stand with a bottom, can I put a small thickness foam padding underneath it?

D*mn! I really like the Evolve 8, but with a display volume of only 4.9 Gallons ....

And I want some cardinal tetras and scarlet badis. (Dario Dario)

According to AqAdvisor (which is not accurate) an Evolve 8 (enter the dimensions) is not even sufficient for scarlet badis.

The thing I like about the Evolve 8, and the Fluval Spec is their built in filter - but the Fluval Spec leaks, and the Evolve 8 is too small.

Such a great idea though

The only thing I really have to add is10 gallons are made that way everywhere without an issue. Also majority of the time the bottom glass is thicker or tempered, I have yet to see anyone have issues.

Standard tank/stand combos will almost never have a solid top it's all supported along the edge portion of the glass, which as you said has the bottom glass supporting the contents. Due to the standard construction of the 10 gallon a foam pad wouldn't be any use. You only use that on a rimless tank design where the bottom rests flat on a flat surface.

I really wouldn't worry. If you really want something sharp get you a 10 gallon rimless
