So I'm setting up a 60 gallon cube that's 24x24x24 in. I've been trying to gather things slowly and a bought a hang on the back filter and a hang on the back for future because my tank is not drilled so I can't have a sump. Come to find out that both the filter and the refugium can't really fit on the tank at the same time where I would like so I was thinking of dropping the refugium. I just happen to be going around on the site to see there were any other options for the refugium and I watched a video where Thomas said he would much rather have a refugium over the filter and that just boggles my mind is that something that would recommend just using the natural live rock in the tank for the biological and having the refugium as somewhat of your only traditional filter or am I missing something
