I was able to watch this one in person and while there is a fairly obvious pitch for Triton tied into the talk I find the whole "modern reef keeping" concept thought provoking. The general knowledge level of the hobby and the community that supports it has evolved so much in the last decade that even the newest reefers are now beyond simply implementing a list of recommended tasks that result in success and now exploring the science behind it all, questioning everything and looking for the next evolutions. As a result, reefers are more successful than ever and "what good looks like" and quality of our tanks has stepped up dramatically with it.
I particularly liked the triangle concept. Proper biology being the intersection of successful approaches to chemistry, filtration, and light. If we take a look at how the community has approached all three of these elements over the last decade or so there have been several evolutionary leaps in each. All of us are likely less than perfect on at least one of these legs and I don't think anyone will say we fully understand spectrum, par, and distribution of light. We are pretty far from understanding the role of even a majority of major, minor and trace elements. Even with filtration, we have a list of methods which achieve some desired results but a lot of unknowns tried to how each impacts other elements of the tank. One of the biggest questions for me is also the role of the potential fourth leg which is nutritional sources outside of light like the addition of nitrate, phosphate, amino acids, carbohydrates and pray or particulate foods.
To his credit, If you really take the time to read and understand Ehsan's approach with the Triton method it certainly comes across as a pretty compelling approach to what I would call a modern reefing method. The method certainly is the accumulation of a lot of what we have learned in the last decade applied to that triangle of chemistry, filtration, and light to achieve proper biology. Certainly, not the only modern method and I find the general evolution of the conversation and challenging old schools of thought to be pretty exciting.
