Acrylic Scratch Removal
I have always preferred to use a glass aquarium. Granted they are heavy and they can be quite fragile if not handled properly. Withouth a proper stand, they can easily stress crack as well. Acrylic tanks are often much lighter and they seem to be stronger as well. But, my focus has always been on looking at the fish, and scratches seem to be a part of any acrylic aquarium I have ever had. It was never very easy to get adequate acrylic scratch removal, or the products seemed to make it worse.
Here is a scratch removal product you may want to try. The video shows the results when using it as recommended for acrylic scratch removal of a severely scratched acrylic fish tank.
