My cousin is looking at buying a 300 gallon acrylic tank with a full sump filtration setup, etc. for a very good price. The tank is in decent condition because on the face of it, it has alot of scratches. The owner said they would polish out. Does anyone know or have any experience elimination acrylic scratches? Pretty much these scratches are the only thing holding us back at the moment of getting it, because it will be in a basement in a built in wall ordeal so the condition of the face is a big deal. Thanks for any info in advance.
