I am planning my sump. Section 1 will be the drain and skimmer the question is should the return be next and the refugium last or should the refugium be next and the return last. If I put the refugium next the skimmer it can be fed from that section, if I put it on the end I would need to tee off of my drain line. Anyone see advantages to doing it one way or the other?
