    Since I moved back to Minnesota I started working at a glass shop and have all sorts of stuff available to me( and I can take home scraps). We have some 1/4 plate glass that I am looking to build a frag tank out of, but have never built a tank myself before. I have watched a ton of YouTube videos and read blogs, but I was wondering if I should do braving on it or not?

    The tank would be about 48" long, 22" deep and 12" tall and would be about 55 gallon capacity.

    Do I need to brace it?, and if so what is the best way? Been thinking eurobrace, with one brace in the middle.

    Thanks in advance!!

    I'd refer to King of DIY for details. But I think that because of that length you would need bracing or thicker than 1/4"

    Here is the calculator I used when building my tank.
    http://www.marineaquariumsa.com/general/glasscalculator.xls

    According to that calculator quarter inch glass will be fine rimless.

    Safety factor is 6 for 48x22x12 with quarter inch. (most references I found used SF of 3.8 as a target.) The key to your success is the shallow depth. Any taller than 14" you would have problems.

    And since you mention this will be from scrap material - make sure you have all of the edges polished before you bring the glass home. Polishing the edges to remove all of the imperfections greatly enhances the strength.
