What do I need for a 220 Predetor tank?

I already have the tank setup and going. I have a zebra eel, 2 lionfish, 2 dragon wrasse, carpet anemone, tube anemone, black spine urchin and a pencil urchin. I have enough power heads and light, I have a good skimmer and pumps. But what else do I need, a GFO & Carbon reactor, calcium reactor, Bio pellet reactor???? Or anything else
