Hey, I recently bought a fiji cube aio 22.4 gal and was wondering if I could run a refugium in my return pump chamber? I’d like to run filter media in the first chamber. I would also like to run bio media, a skimmer and a heater in the middle chamber so that doesn’t leave me with much room left. I have a mandarin dragonet so I need a refuge to house the copepods. Is a skimmer necessary since it’s a nano tank? Please let me know your thoughts or ideas. Thanks
