I have a 120 gallon tank 48 x 24 x 24. There are 2 depressed areas for a glass canopy that measure 22.15 x 22.25. I cannot find the correct glass canopy, any ideas? The closest I could find is Pet Supplies and Fish Supplies at That Fish Place - That Pet Place Item # 212133 / Manufacturer Part # 35481 specification state Width 22.25 in. Length 22.75 in. Any ideas?
