As I said, the effort may be too much for suh a cheap tank. The only time I would suggest it is if the tank in question is for a specific purpose or is hard to extract from it's current location. I had a crack in one of my tanks in my MaRS retail multi-tank setup that I had to use this method on, as it would be MUCH more difficult to replace rather than fix. So, unless you have some spare window panes sitting around the house that would fit it, I would just go and get another 10gal tank from Wal-Mart or PetSmart or some other cheap store. Being a very small tank, craftsmanship doesn't play much of a role, so all 10gal tanks are pretty much the same.
