I just euro'd my 120g (48x24x24, lwh). I stripped out the glass bracing it came with and took off as much of the old silicone as I could. Then I had 3/8" glass cut into 2 48"longx3"wide for the front and back and 2 17 7/8"x3" for the sides. I actually siliconed them onto the top of the glass panels, as the bracing it came with was on top, as opposed to inside. I siliconed a thick bead onto the tops of the glass panels, and then placed the front and back braces on as they stay up without support running the whole length of the tank, and then siliconed the side braces in. I let them cure for 48 hours and then trimmed off any excess silicone, then siliconed the black trim back on the top that it came with. Seems really strong to me, but then again I am not 1200lbs pushing on the glass either.
Well, yet.
