The problem with plexi is that the side facing the water absorbs water since acrylic is poris and dose absord some water... then the side thats facing the water sags downwards, unless you flip the pannels every month they will warp bad, and for it not to you will have to go with 3/8" or thicker but this still will warp...
I would do with the glass tops. they have a plastic hindge that allows you to flip one side up and they rest on the cross braces. my tank didnt have any so i put some in...
