so i purchased this 200 gal acrylic tank, 67.5"x19"x36", for $200. its in decent shape but needs some work. It used to have trim on the tank but majority of its off. How do I go about removing the rest of the trim with out damaging the tank? And what novous is the best to use? there are not any deep scratches but small ones that i would like to get rid of before i fill the tank. Any inputs would be great.
