[the marine apprentice]

im not to sure if this is in the right place but here goes. i have a std 90g drilled with overflow. it has 3/8" glass all around and dont see any bubbles in my silicone and i am wondering if it would be a bad idea to try and take the black rim off the top. i love the look of rimless tanks and would like to do mine like that. any info would be great. also there is no bow at all in the tank incase you are wondering
tks
