okay so i work next to this Asian food place and im in the getting lunch and i notice they have a 135 gal tank and stand filled with crap and sitting in the back. i ask what they want for it they said it holds water and they would let me have it for 200 bucks, i offered 100 due to the scratches everywere and they agreed cool. so i am gonna reseal it tommarow just because it realy looks like it needs it but is there anything i can do for the scratches at least on the front lol. and its not predrilled i wonder if i should go overflow or cannester any tips help
