This is the only sensible way to do this. If you try it seperate O/F and return pump for your fuge, you will have to allow for drain down with a power outage losing valuable volume. Running as Bluespot suggests you can use full volume and do not have another pump to heat you up or maintain. To get the most of pod production have the drain from the fuge aimed at the first baffle after your skimmer.
So, Steve, you're saying that I will have to have a low level of water in the refugium to prevent flooding if I have the fuge on a separate circle?
A question about check valves.. would they work in a setup like this to stop downward flow in the event of a power loss event? I have a whole house generator that kicks in after two minutes, so a check valve would only have to hold for those two minutes. Is that viable?
