Hope for old scratched tank?
Recently acquired an old 55 gallon tank, it has some deep scratches and a ton of fine scratches, filled it up quickly outside after dark and shined a tank light above it and it looked like it had cobwebs stuck to the glass everywhere, it was bad. The glass is also thicker than normal, I was told it was very old.
So my question is, is it worth my time to try to fix, and if so what methods and materials work best? If not, then what kind of uses can I do with the tank? Use it as a grow tank and not for show?
