Somehow something harder than my glass got stuck in the felt pad of my Great White Magnavore - I was sick and didn't pay close enough attention when cleaning my glass - i have a bunch of very fine scratches (wont catch a nail) on the outside of my tank now. Ive read Cerium Oxide is the material for the job along w/ some water and a buffing wheel.


anyone ever done it? howd your experience pan out?

This is for a 210 Tall Oceanic.
