Hi Randy, you answered a post I made a while back about the fact I employ no prefiltration at all(I do run a skimmer and Oxydators with an ATS) and you replied something along the lines that neither do you and that you had 2" of detritus in your sump (forgive me if I don't quite have that correct) I would like to hear more on your thoughts and experiences not running prefiltration if you would be so kind to expand on it please. Thank you.
