I am currently running a mag 9.5 for my return on a 90 gal and a 20 gal refugium. I am also running the black filter that came w/ the mag pump. My question is is this filter keeping the pods that are in my fuge out of my main tank or do they still manage to make it to the display. I would take it off but worry that I might end up pumping some cheato into the display. Any suggestions?
