used tanks

[ayrton]

I have 2 20 gallon and one 10 gallon tank that all leak. These are second hand tanks that someone gave me. Is it worth while re caulking them or should I just throw them out. What kind of caulking should I use and any special tips and how to do it.

Thanks very much.

You can use silicone I or any silicone that says it is aquarium safe or safe for food or water containers. They would make nice freshwater or nano-saltwater tanks. They would also make great sumps or refugiums for a larger tank, say 55 or larger would be a good starter. If nothing else you could make terrariums out of them and give them to your female relatives for Christmas. What to do, what to do?!!!
