Cerium Oxide
 

I have a few light scratches on my glass tank which is currently empty. My fingernail does not hit the rut so it looks like they may be removable. I heard cerium oxide will work and was wondering if anyone has had any experience with it and also, where I can purchase it in the Lower Mainland.

try a jewelry polishing shop.

Cerium oxide is for polishing stainless and ceramic use jeweler rouge it is for polishing jem stones and will polish out scratches in glass use a drummel tools with the cotten wheel it works like a charm. tank will look like new I have done it before and when I do a realy large water change I have to do it to this tank I didn't notice some scratched up areas on it before filling,
I can live with it for now. Just makes for photographing in some spots a bit hard.

A rock shop or lapidary store will have it. I believe there is one in Cloverdale.

be prepared to spend a few hours buffing up your glass as it takes a bit of elbow grease to take off those scratches.
