You may be able to reseal it with out draining the whole tank.Just drain it to below the leak,Then dry the corner compleatly.Use some aquarium silicone and push it into the seam with your finger from the inside.You may need to cut away some of the old sealant first.Don't be stingey with the stuff.Wait till it dries(24hours) then refill the tank...If this does not wirk,you will need to drain the tank,scrape out all the old seal with a razor knife,clean and dry the seam,then reseal the entire joint.....
