what is the proper order of mechanical/bio/chem of filtration ?

[RioReefr]

I know you want to mechanically filter large particulates (ie filter sock/pad) FIRST, then the smaller particulates (smaller micron pad) from the water. Then the protein skimmer, then....

....after the water leaves the protein skimmer, would it make sense to then pass it through activated carbon, then some phosphate remover, then through nitrifrication media (ie Marine Pure) before the water returns to main-tank?

Once it gets down to the "dissolved solids" water, does it matter what media it flows through in a particular order?

After the mechanical filtration I really don't think it make any difference.

The only filtration I use, and I think most reefers, is the live rock, protein skimmer and CUC.

With the addition of a filter sock for a few hours after maintenance day to catch any large particulate that I might have stirred up.

I don't think it really matters once you get the 'chunks' out through whatever mechanical filtration you use. As others have suggested, many rely just on a skimmer + live rock/sand to do their filtering. Beyond that, they use specific other things for a limited time for a specific purpose. Going to stir up some stuff in the fish tank, put in some filter socks; water discolored, suspect 'chemical warfare' among corals or need to remove some medication, run some carbon. Phosphates running higher than you'd like with signs of excess algae growth, run some gfo for a while.

Others run these types of things plus others like biopellets or carbon dosing on a continuous basis. I'm not sure there is a 'right answer' but, just give some thought to why you're using whatever you decide to use and, to the extent possible, test the impact of your using it to see if it is really accomplishing what you hoped it would. Also, observe your animals as a 'test' to see if the 'result' you achieved is having a positive impact on your livestock.
