Today, I purchased a 55 Gallon Acrylic tank, complete with stand, filter and lights for eighty dollars. The tank is pretty roughed up, but I knew it was possible to clean up an acrylic tank. Even if I cant, i figured the stand and extras was worth the eighty bucks. Now, my question is, how should I clean it? Its foggy, and has more than a few scratches. Scratches dont bother me very much, but If I cant get the tank cleared up then I will probably just buy a new 55 Gallon tank. I would love to save it if possible though, so any help would be appreciated!
