I've been doing this gig for over 20 years, and I still learn something any day.
Also, the term easy is relative to what you are doing. In some respects salt water is just as easy as fresh water with the only added variable being you have to mix salt. Wow...big whoop. Actually, I'd happily argue that damsels, triggers, etc., are likely hardier than many popular fresh water fish and can actually tolerate a wider range of certain parameters.
Take a salt water tank that only has softies and hardier fish in it. All you really need to do is basic maintenance such as weekly partial water changes, and nothing else. You don't need to dose the tank with additives or watch alk or magnesium levels. Mixing salt is the only extra work required - that's it. With basic light and high nitrates sooner or later mushrooms and coraline starts to take over, and the occasional hair algae and cyano outbreak comes and goes because there's too much competition. I've seen some really cool 'wild' tanks like this that are covered with purple mushrooms, giant aptasia, patches of macro, wall to wall rock anemones, and coraline a quarter of an inch thick on everything. Absurdly low maintenance, aside from periodic water changes which should be done on fresh water tanks anyways. Not everyone dreams about keeping chalices.
On the contrary, I've seen veteran reefers with a Masters in biology or chemsistry lose thousands of dollars worth of SPS over a period of days in established tanks due to RTN and absolutely no cause what so ever. I've seen just as many of these guys bail the hobby as newbs.
What is RTN?
