I happen to like a little bluer light on my zoanthids, so I use a 250 watt 14k Hamilton ( PFO HQI ballast)with a 55 watt pc actinic.
Seems to bring out the colors.
I currently am not using any additives or feed very much.
Just do regular water changes.
I do have alot of flow in my zoanthid tank.
I have a Korilla 4, a modded Tunze 6025 and a modded maxi-jet 1200 and I use a mag 7 for a return pump from the sump.
