Custom eurobrace/plastic trim removal

[seth.s]

I’m slowly building out a 180 gallon tank that I got for $250. The tank has a plastic rim but also a eurobrace that goes along the front, back, and sides. The brace is 3/8” thick and 1.5” wide. What further bracing would I need to be able to safely remove the plastic rim? I’m more thank likely going to reseal the tank so I plan on having it apart.
