I followed the advise I got here on AA when I had the same problem. We took the glass top back to the LFS
and got store credit, which we promptly used. However, my can't just keep it simple, husband made a few adjustments. I did not like the look of the white egg crate for lighting, since where I placed my tank when you walk down the stairs into my living room it is the first thing you see. BUT we found the silver and yes we noticed it flacked off. Here is where my husband got creative. He cut the plastic with a tool they use for cutting foam. It looks like a solder gun with a thick wire on the end. It stunk to high heaven, but it made a beautiful smooth edge (which we needed for a bow front). Then to take care of the flaking he sprayed several thin layers of clear spray paint on it. It has been a few months now with frequently lifting and touching, banging around dropping on the floor and cat inquiry and no flaking. On the pic you will see a black patch, that is just solid thick foam used for cabinet liner. I did not like the algae growing in the overflow shoot, so I though if I got rid of the light going in there it would slow the growth down. I know this is a little extra work, but I am very happy with how it looks, since it is the focal point of the living room. Hope this helps.
