I know in the past the main theory was to have a huge sump and get as much flow as possible thru the sump. I have been doing a lot of research for setting up a refugium with live sand and algae. Some say flow inside the tank is more important than a high flow thru the refugium and some say keep high rate thru the refugium. It seems like a slower rate would allow the nitrates to be consumed more effictively, what are your opinions?
