I need to know what exactly I should put in my small CPR hang-on refugium. I'm getting ready to put fish in my tank after I come back from vacation in a few weeks after I lost ALL of my fish to ich . It comes with the pumps, power heads and all. I just need to know what to grow in it and which inverts to add. As I said its a small 13.5L X 4.5 W X x L
