You know its obvious that you can have a refugium next to you tank, not necessarily underneath your tank by seeing some pix on line of others peoples set up. so how can I plumb into my tank or sump to refugium next to my tank, I cannot have any overflow I have a corner bow front tank so i have to place a custom tank or refugium on a stand next to my tank. I've seen a nano system on a cabinet with sump underneath and the refugium to the left with no over flow. Does anyone have any suggestion or designs?
