To properly sterilize a tank, you must treat everything with bleach: aquarium, plumbing, pumps, filters, live rock, sand, corals, etc. I doubt this is a measure that many reef aquarists would want to undertake. There was even one documented case of a group of Egyptian spiny-tailed lizards, Uromastyx aegyptius, contracting Mycobacterium marinum because they were housed in an enclosure that was once used for fish (Morales, Dunker 2001). The tank was stored completely dry, but un-sterilized, for some time, and this bacterium managed to survive and infect the reptiles. This goes to show how truly resilient this pathogen is, and how extreme sterilization methods must be undertaken to be effective.
