There are a lot of successful reefers that do very little, but perhaps I should clarify that point. I mean to say that they have a very simple and straightforward approach to reefkeeping. Jason Fox, for example, basically does almost nothing but water changes! The Reefbum interview left them virtually nothing to talk about because he doesnt do anything! Our very own Kenny and Rich Ross also have very simple and straightforward approaches to reefkeeping. Sanjay Joshi, Jake Adams, Mark Van der Wal - more examples.
I'm not saying these folks don't do a lot of work or have incredibly deep knowledge. I'm not implying, by any means, that the hobby is easy. But I think water changes, high quality light and flow, reliable equipment that's well maintained, live rock - these things, applied with knowledge and intention, get you about 90% of the way there most of the time.
