Hi all. New to the forum, been doing fresh water tanks for about a year now. I just picked up a 125g tank from a friend of mine. It would be a beautifull tank except that the people that he got it from must have used steel wool to clean it. The entire surface of the tank is covered with tiny scratches. There is nothibg that you can feel but there is no spot that looks clear. I have a drill, buffing wheel, and cyllium powder, but it does not seam to be doing the trick. Does any one know how i might be able to get these scratches out. I would love to get this tank set up. Thanks in advance for any advice.
