I understand the problem with getting used tanks and trying to figure out what brand lid will fit the tank.
If the lid is too short on the long ends of the canopy, you can buy the clear plastic back strip and cut it to fit your tank length. Be sure to buy the correct size, it comes in 1/8" and 3/16", depending on the glass thickness.
