There a few deep and big scratches in my 300gal tank it is bugging me. U can clearly see ones the tank is clean how do I fix it. The scratches r on the inside
If this is glass, you have to live with them. Acrylic you can polish out. Someone else asked a similar question the other day and I thought it would be interesting to contact one of those windshield repair places and see if they have an option to fill the scratch.
