Boiling (literally 212F+) for 20 mins or bleach at sufficient doses and sufficient time will kill almost anything, however, given a choice, I'd boil. It's easy, it's inert and it works.
In many cases, people don't have a choice, but I've found that boiling always gave me a sterile object for the tank.
