I am thinking about using 1 of my emperor 400s to run GFO and carbon. The second I might turn into a refugium. Would I be able to run GFO in an emperor 400? Will the GFO be as effective as if it ran in a reactor? Does GFO suck up trace elements as well as phosphates? Would I be better off if I only run GFO without running carbon? Thank you.
