So I learned my lesson the hard way this morning. I used a magnet cleaner on my tank and I must have got a small piece of sand in it. Put 2 nice long scratches in my tank. On the lighter side they are on the outside..(i know go figure) so I'm hoping I can buff them out. The tank is glass. Anyone have any ideas to get rid of the scratched, and for an alternative to the magnet cleaners?
