thanks for the reply SevTT. what system do you use? Right now I'm just using the Berlin method with carbon in a mesh bag in my sump, but looking for a lower nutrient environment. Whether I'll use Zeovit/vodka/GFO/etc. is still up in the air.
Basically, a modified Berlin/Jaubert/whateverthehell system.

DSB, fuge, LR, somewhat weak skimming, carbon dosing via vinegar in kalk topoff, activated carbon and some aluminum-based phosphate remover in pantyhose in my sump, and not freaking out when algae or whatever does have a small bloom. But really, the important thing is having a diversity of life,
particularly microlife, that actively seeks out detritus and consumes it. Once the tank is nice and crawly with worms of all sorts and pods of all sizes -- not to mention snails, hermits, and the fish themselves, along with, yes, algae and diatoms and such -- you can throw an astonishing amount of food in there with little effect on the water quality.
I don't use any kinds of amino acids or whatever -- a proper diet is chock full 'o amino acids in balanced levels, that's what protein
is. And that's how corals on a reef are most likely getting them, not through direct absorption. I use a lot of cyclop-eez and mysid shrimp, and selcon for HUFA supplementation.
Carbon dosing via vodka or whatever does exactly this, at the absolute lowest level: it provides for the growth of bacteria that float in the water, consume your nitrates and phosphates, make more bacteria, and then get skimmed out and/or consumed by your corals. Nutrients are converted to nutriments very rapidly.
Even your rocks just provide a platform for more life to grow on and stratify. If you approach it like you would playing the game Spore, building an ecosystem from, literally, the ground up, filling up functional niches, you can't go too far wrong.
