Ok, well I feel pretty dumb for having to ask this... Is there any way to tell what type of tank that I have as far as manufacturer? I purchased this tank about three years ago and have broken one side of the glass canopy. I tried to swipe one from the All-Glass with sump, and it doen't fit. It seems that the center brace on the AGA is a little wider than on the unknown. The glass top had a clear plastic handle if that helps to identify who made the top. I can't find enough information about the glass tops other than to know that it isn't AGA. The aquarium uses black silicone if that is an indicator. Other than that, I have no clue and can't replace the top. Any help would be greatly appreciated.
