i just wanted to post up a little info i recently found out. it is very possible to remove even deep scratches from glass. I bout a 210 that i was going to use and it had some bad scratches in it. I found a company called "shine glass renewal" that charged only $100 to do the front panel of the tank that is 7' x 2'. he was almost done and about to start polishing when he cracked the glass due to the heat. however, he did pay me for the cost to replace the tank. it did leave some slight distortion but that is better than a deep scratch that holds algae. he had already polished one end of the tank and removed every single scratch that was in it. he spent about 4 hours doing it. for those that want to try this, he used a 7" angle grinder with sandpaper and a buffing wheel. at one point he was using 60 grit sandpaper and slowly worked his way up to 2000 grit and then the buffing wheel and a polishing compound i'm assuming that was cerium oxide. like i said, he spent about 4 hours doing it so had he not broken it, i'd say it was well worth the $100. I just wanted to share with those that have come across this issue and put a little more info out about it.
FYI, i used the money he sent to replace the tank to buy a starfire panel to put opn the front instead of a new tank. so i think i came out pretty well in the end.
