I am in the process of figuring out how I am going to setup my fuge. I am leaning towards an external side tank fuge. Fill it with all the junk I can find and let it be my filter. I appreciate the offer and will take you up on the Chaeto. I am a refugium nut, I like 'em better than the display tank and have done all sorts of "experiments" with different setups. In the end I have found that the more diversity in the refugium, the better the health of the main tank. I miss my old fuge, I wonder who owns it now, I would like it back.....
