Nobody has "the answer"...which is a source of endless frustration for newbies.
One of the signs of a maturing reefkeeper is they stop looking for "the answer" and get on with figuring out what works -for them-. Very little about aquariums is really "known", in the sense of repeatable experimental evidence. It's mostly just opinion; some much more informed than others of course.
I think it really helps if you try and get the big picture and work back from there. For example, the ever-popular topic of "filtration" is really just a matter of imports and exports. Everything else, water changes, live rock, live sand, plenums, skimmers, carbon, ATS, algae sumps, you name it, they're all tools to that end. None of them will magically export everything you'd want.
So newbies, quit asking for the "right" skimmer or the "right" amount of live rock, or whatever. It doesn't work that way. Every tank's imports are different, so every tank's export needs are different. -You- have to figure out, given the characteristics of the various export tools, which ones are likely to work for -your- tank. Then -you- have to try them to see if they'll work -for you-. There is no other way. And this idea applies to all aspects of reefkeeping. Figure out what is happening/needs to happen, then look for tools/techniques to accomplish that.
No Reef God, book, or web board can do this for you.
