Pictures, yeah, I can't post them now but I will. I did post a couple, let me see is I can find the forum. But anyway....I think cycling your refugium during the same time as your DT is the best way. I did it with my DT already est. and have to cycle the refuge all over again before circulating it into the DT. So before you add fish or anything that is the best way. Let me see if I can find the forum I posted my pics under.
