Did like a 80% water change today and threw all my zoanthids in there. The light is temp, I don't think it has the oomph to keep the zoas happy. This is about 15 minutes after the huge water change so water isn't perfectly clear yet and about 10 minutes after I dropped all the zoanthids in.
Some quick info about the tank, I cut a 11" notch in the back of the tank and added an external overflow box. There is no equipment in the tank besides the two returns that come from a 740gph pump connected to a SCWD.
