Here's a pic of the sump, the skimmer is starting to produce skimate again.
My yellow tang looking a little skinny. Need to work on fattening him up. I feed emerald entree and Pacifica plankton usually every two days. And maybe once a week I rip off some nori that he eats. What else can I feed or should I be doing?
I also keep moving the fox coral around, it's hard to find a low flow spot in my tank.
