Replacing plastic tank center brace

[jason604]

Hi I need to replace my 75g tank center brace with a glass piece becaue it is blocking my led lights. Has anyone successfully removed it and has no problems in the long run? Do u have any tips in doing this? Do I have to saw the brace off while the tank Is empty? Should the glass I use to replace the brace 1/4" or 1/2"?
