I'm in the process of installing baffles into my 29g sump. I have a HOB Coralife skimmer that does not need much space in the first compartment. The first section will have my filter sock, and skimmer then to baffles, and the return then refugium. I want to make the refugium as big as I can. How much room do I have to have for the center return section? I have a Mag 7 pump, and gravity fed ATO.
Thanks
