Has anyone replaced their center brace with something smaller? I have a 150g and my center brace is 1/2 inch glass, which is ok, but it is about 16 inches wide which makes tank access pretty inconvient. My tank is in wall, so I can pretty much modify it anyway I want since the rim if the tank is hidden by the wall. I would like to get it down to somthing a couple of inches wide, but it can be as thick as needed. The tank is 60x24x24 and made of 1/2" glass, with a one piece rim on the top and bottom.
