What are people doing for filtration? I've heard both ways. Use live rock only. No filter pads. Or just live rock. No filter pads at all. Right now I'm using filter pads before and after my fuge.. Of course fuge is built into my sump.. Debating on whether to take the filter pad out before the fuge.. Will help anything like Copepods or small animals to enter the fuge safely... What are some thoughts?
