Fixing scratches?

[Delphinus]

With glass, I don't really know. Supposedly there is some kind of kit you can buy to buff out scratches from car windsheilds, but I kinda doubt it would work real spectacularly.

Acrylic of course should be possible to buff out.

My 75g which is my main reef, the tank is pretty old and it's scratched up pretty badly at the bottom (I think the guy before me had a silica based DSB in there). If I keep it spectacularly clean (razor blade clean) then you don't notice the scratches as much. Of course, not having a scratched tank would be much nicer, but whatcha gonna do..
