New tank 300 gallon

[golf nut]

I gave Derek at Miracles Aquariums a quick call to discuss other things, I asked him about the tank you wish to build, in his words using 3/4 glass you would need no Eurobracing at all providing you are not running a wavebox, which looking at the clean look you want will not be happening.

Yeah no Wavebox.

3/4 inch glass is what I was looking at using

I was thinking I would brace the tank with a piece of glass 1 inch thick at the top which covers all the edges.

Not quite sure how I would get a piece of glass cut like that though.

Acrylic might have to be the way to go if I brace like that.

I would love to have no brace for aesthetics but do you really think the tank
would hold without?

Tank is going on concrete in a basement with dedicated flood drain but a 300 gallon burst would definitely overload the drain.

I guess there are two ways to look at it, He would build a tank for you exactly as portrayed and fully insure it against issues, however if you build it , even if they were 1 1/4 thick then it is your baby.

Structurally speaking that size of tank is fine without any Eurobracing if built correctly with 3/4 glass.

3/4" inch rimless would be over speced.
5/8" rimless would meet acceptable safety standards.

The major consideration is the height at 20"

I prefer over speced, but you will pay significantly more for the 3/4" and if it's not necessary, why bother?

If your interested in how I designed my 300g, you can read my build. If I had a "do over", I would have gone rimless.

What's appealing to me about using glass a little thicker than needed is the greater width to all the seams. I'll be doing an inner eurobrace on my next big tank on the bottom...sides would be too ugly. But a 3/4" seam would be very strong I think.
