I have another post about a haze in the glass I cant get out so I'm just seeing what my options are. I've seen videos on youtube of people changing panels of glass on their aquariums but all the aquariums seem to be 55 gallons or less. Just seeing if anybody has experience with changing big panels of plate glass. It would be the front glass on a 180 which is 6'x2'x1/2". Any advice would be greatly appreciated.
