I've been thinking of adding a refug to one of my tanks and was wondering where most of you put yours? Above for gravity feedback to tank or below for a gravity feed to the refug? Powerheads also seem to be different some what movement others a gentle passing of the water through it. I'm at this point planning on a 20 gal with a small PH on lowest flow besides the water in and out movement. Welcome all thoughts
