Re: Having trouble
You could go to a good (locally owned - petco and petsmart don't have them) pet shop and buy a clear vinyl plastic back strip - the kind they have on hinged glass aquarium lids. Then have your glass (or another piece) cut to fit with the strip. You can easily cut or drill the vinyl strip, just be careful to make sure that the strip fits tightly.
