I'm out of aquarium silicone to glue the airline to the lid of the bottle, Can I use epoxy instead?

It would probably be safe to use epoxy. Most epoxy dries very hard, thus very unlikely to leach anything harmful in to your aquarium. But being the worrier that I am, I would take the time to buy a small tube of aquarium safe silicone. You can buy small tube at ACE Hardware for less than 3 dollars. This way, you know you are safe.

I drill a 3/16" hole in the cover, put a couple drops of super glue around it, and force a airline tubing fitting used with the white airstones tightly up against the cover. Let it dry about 5 min and its ready to use, without any unsightly gobs of silicone sealant. Its never caused me any problems, and it won't leak! :hehe:
