I have a 125 gallon FOWLR with an emperor angelfish, powder blue tang, yellow tang, and blue tang, all juveniles. I run a skimmer that is for a 300 gallon tank that is being fed by a 1050 gph pump. With this large of a skimmer, do I need the filtration sock or can I just vacuum the debris out of the sump and let the skimmer take care of the rest? Thanks!
