The biggest thing in my mind is that different things work for different people. too many variables are involved for any one method to be blindly correct.
Coral load, water change schedule, salt mix, type of corals, food used, evaporation rate, skimmer efficiency, ect..all come into play here. I run a ULNS system so Trace is VERY important. I also only change my water every 4 weeks unless I notice a problem. Some will say that this schedule is insane, yet anyone who has seen my tanks will tell you I have some very impressive specimens that are thriving. My 180 has been up less than a year and is performing beautifully..another year and it will be a TOTM (hopefully)
Fishdoc has excellent specimens and does relatively little compared to my regiment.
Take notes, research what your critters need, and use those items. I have goniopora, clams, sponges..so Iron and Manganese are important to me. if I were just running softies and SPS I probably would not supplement it, so as an example the moral is food for thought, try different things under educated assumption, and keep what works.
