I'm currently running a red sea reefer 350 with the media cups instead of socks. I started with floss in each cup. One of the cups is hard to get to with the stock ato reservoir so I filled it with live rock rubble. I'm wondering if I can just put live rock in both and not have to deal with floss anymore?
I have a skimmer, carbon reactor and refugium as well.
