I would assume the refugium will perform similar to the algae turf scrubber? I assume that’s what ATS stands for?Carbon! I dont use it anymore as I installed an ATS (which is another thing you could explore) but I liked running carbon as it keeps the water clear. I also used a little GFO now and then.
