I am setting up a 120 gallon DT in a 160 gallon total system. I already have one fish that is 50/50 with a reef setup. So I will either be turning this upgrade into another FOWLR with quite a few fish or a build with some corals that would be limited to softies that most fish will not nibble on due to taste and etc. This brings up my question, for a FOWLR would a protein skimmer or a refugium be more beneficial?
