I'm currently setting up a 20gal mixed reef with what will probably be a 20gal sump/fuge. I've got a HOTB overflow box that is rated at 600gph. What I'm not sure of, is what size return pump should I use from the sump back to the display? I know you want pretty low flow through the fuge, sooo... what would you all go with?
Thanks!
