Curious to see who else has removed their standard brace and replaced it with acrylic (or other?). I took a standard 75 gallon and replaced the center brace with 2" wide 1/4" cast acrylic. I used nylon bolts and nuts to fix it into place while the tank was empty (4 per side). The tank has been filled for a few months now and there are no ill signs whatsoever (not that I expected any). It's been great because there is NO shadowing in the tank like you'd typically get. This has me tempted to do something very similar with my 300DD (the frames are super wide, argh!) but obviously I'm extremely scared because of the consequences of what could go wrong. Water draw-down and partial cuts would probably render my fears mostly moot... but still.
Have you done this or something similar? What about on a tank that's up and running???
