Just get a larger storage container at Dollar General and move everything to it temporarily.
Try resealing just the inside seal and see if it stops the leak. You just cut it with a blade, making sure not to cut the silicone between the sheets of glass. Then apply the silicone, I'd recommend Dow Corning 732 silicone, and run your finger over it to smooth it out. There are a million YouTube videos showing this process.
I'd let it cure for a week minimum and then water test it.
