Tank with a leak?

[donlankford]

I was just offered a 50 gallon FW tank that has a small leak in one of the corners. Was wondering what i could use to seal the leak that will be safe on the fish? Will it still be strong enough to hold water after the leak is sealed? And it is just the tank so need some recommendations on equipment (pumps, filters, lighting, etc)?

You could redo the silicone and see if that fixes the leak, just be sure to use aquarium safe silicone
