Age of tank 1 year
Skimmer: Hydor Slim SKim
nitrate:20, a little high after moving the tank,
ammonia: 0
temperature: 78-80
Water source {ro, ro/di, tap} ro/di
Salinity: [eg, 1.024] 1025
Alkalinity: [eg, 8.3] 8.4
Lights [mh/T5/LED, other] LED panorama pro, 2 modules,
Calcium: [eg, 420] unknown
Magnesium {eg, 1500] unkown
Dosing?[list other additives used, if any]

Xenia are a tricky coral to diagnos. From my experience, a mature tank is preferred and higher than average nutrients present. When they are in the correct & preferred environment, they will grow like gang-busters. With this also being said, once they are in decline, it is difficult to reverse the course. Personal experience with this coral.

Xenia are strange. I skim and cant stop them from growing, I actually have to throw them away, but I have a friend with a tank with no skimmer and they look fine, but are not growing at a rapid rate.

So in some cases I think its the nutrients, while I feel they like high lighting and flow as well. I have read they like iodine, but I personally have never dosed that and wouldn't recommend it unless you can test for it.

How old are the bulbs and are the Xenia in about the same place they were?

I am new to soft corals and my xenia are doing the same thing! They were growing like crazy and split several times in the first couple weeks. This past week they started looking shriveled and white and they aren't waving their hands as much. I did a 10 gallon water change out (55 gallon tank) and have wondered if that bothered them. My nitrates, nitrite and ammonia are at 0, salinity is a little low at 1.024 (but figure it will come up gradually over the week). Any ideas as to why it would change so quickly??

I have had one kind of xenis do fine and another melt away for no appearant reason. Both I have had for many months. I have pom/pom, and red sea doing fine. My common tan xenia just croaked after months of growth.

Really? I head they don't actually have mouths. Although I've heard that the pulsing may help them absorb nutrients.

Yeah I've heard that too, but it still has never failed to help establish Xenia for me. Probably just dirties the water. Also, I find that I don't have to dose it after the Xenia establish.
