Hey all, just getting my fist SW tank, a JBJ 30, ready for something alive besides some rocks. Just wondering, I bought it used and have no docs for it, are the 'refugium?' columns good for anything other than the heater? Thinking about a small skimmer (not sure if it is needed) but a true refugium has more going on. Anyone doing anything more with that area?
TIA, Jay
