Scratches on glass aquarium

[corpusse]

Buy a new tank.

There are things you can try cerium oxide. If they are really really light scratches you may have some luck after many hours of labor, but with the time you spend on it you'd be better off to buy a new tank.

I once thought the same thing btw. I had a cheap 180 gallon tank that I could not remove the scratches from. I would never attempt to remove a glass scratch again. If my current tanks get too scratched up I will replace them.
