I have had a duncan in my tank for the past year. No Matter what I do I can't get this thing to grow at all. lighting is t5 HO 4 by 24 watt UV lighting. SG is .24 Mag is 1370 cal is 415-420 PH 8.0 to 8.1 KH 9-10 I feed a mixed diet from mysis to krill to rotifers still nothing. Any advice from people who have duncans or know to to grow these corals would be really appreciated.
