If Fong's reef is the best example of not doing water changes and using this method that you can find, compare his photos to those of more traditional methods. Especially pay attention to what SPS corals are not in his tank (deepwaters, echinada, lots of milles, pearlberry, etc - the harder to keep ones) and especially pay attention to the color contrast in the acropora - it is very non-descript and sometimes not even there. Check out some of the tanks of BigE, JBNY or Copps and look very closely - these guys do a good job of having accurate, well-done pictures. If you look hard enough, or for long enough, what impressed you at first will not be so impressive anymore - lots of mature average corals with slightly greasy pictures and the SPS have only so-so color. (I am still guessing that you are wanting to have a good portion of SPS since you don't need to do any of this really for LPS, softies, montis, birdsnest and stylophora)
Also, this guys says that he does occasional water changes. What does this mean? A large water change every few months is occasional, but not that out of the norm for some. It might be a good idea to find that out.
BTW - I am not trying to talk anybody out of this. Just trying to educate. There are lots of folks who tried something like this only to find out that they did not really do much, or were a bit of a detriment, that wished that they would have known more when they got it.
