i had a tough tank tank made, and yea all of it was new clear glass while some people use tinted glass on the back and sides, if its all clear you can just turn the tank around during your next shift if you get a big scratch in it. haven't had one from greg yet though.
i found lynn from tough tanks great to deal with, yes they're a little more expensive but they are alot closer to me than greg is and the quality of work done was great. best thing is that they have a cheep aquarium supplies store there to browse through when you pick it up
