Aquarium Repair and Modifications in Calgary

This is how people develop hoarding problems, when they assume something has value when in reality it does not, hence why it just "showed up". The cost of disposal is likely more than it's value.

However with that said I can also offer some more useful information.
First others are correct tempered glass can not be modified in anyway no matter where you take it. However how do you know it's tempered? It's unlikely the whole tank would be unless it's some kind of special build but virtually no tanks are ever fully tempered, some tanks do have tempered bases but that's usually as for as it goes. So if you're planning anything relating to using the tank, first confirm if it's tempered.

If the tank is something you want to use then consider just replacing the viewable sides with new glass (doesn't have to be tempered provided thickness is correct. You can reseal the the rest of the tank without disassembly, simply remove the silicone bead from the inside and reseal with the correct silicone. However don't go down this road unless the current tank size is something you desire. If you'd prefer something closer to 100 gallons consider buying a new 90 gallon, brand new price is typically $300 or less for a standard 90 gallon. You can get used ones in good shape for half that or less. It's much cheaper to buy standard tanks than build custom ones yourself.
