The show is meant for entertainment, not to teach people the proper techniques for fish keeping. The show has never claimed to be for educational purposes. Take the show for what it is, entertainment, and watch it like that. As has already been said, there is tons of stuff still left on the editing room floor. We probably don't even see 10% of what goes into making one episode.
As for tap water, I guarantee there are plenty of people on this very message board that still use tap water for there tanks. I have a feeling that 30 years ago when people had saltwater tanks they weren't using RO/DI. I know my uncle didn't and he successfully kept fish for 10 years.
