Help please, PomPom xenia problems.......

[PeculiarClown]

Well,
My PomPom xenia, in three diff. tanks are just not doing as well as I'd like.
They rarely pulse anymore and their polyps (hands) aren't full and fluffy looking anymore.

One tank has VHOs, and the other two PCs...... all contain zoas, LPS, ricordea, shrooms, other xenias, gorgonians, etc. that are all doing fantastic.
My water params are amm. 0, trite, and trate 0 or slight trace.
I dose with kalk and purple-up, reef plus, Seachem ess. elements..... feed DT's, frozen food, Kent phyto, chroma, and zooplex.

Any clues???

Thanks!!!!!
Jen

BTW,
The xenia is in my 30L at home, a 150 at work, and a 75 at work.
3 completely diff tanks, only common factor is me, lol!

My white pom-pom xenia died in all tanks in the same time, when all other corals were OK... Half of year later it restored in one place.

It grows well at SG 1.026, 76-82F, 6-15 dKH (extremities, N is 7.5 - 11.5 dKH), NO3 up to 80 ppm (didn't try more), PO4 1 ppm (also didn't try more), pH 7.8-8.4, Ca 360-460 ppm, Mg 1100- 1650 ppm.

What I had - relatively high flow around it, medium to high.
Low PC lights, but it did well in direct sunlight.

What else I have - grounding for stray voltage in every tank, just in case.

Could be some reaction on other corals, I don't have too much zoas or leathers at all. Water changes, more frequently carbon for a some time - to see if this make any difference. Or try to place it in its own pico, without zoas, leathers and stinging neigbours and see, how it will be doing.

HTH.

What are your Calcium, Alk, PH, and Temp readings like?

Fluctuation in any of those are pretty typical culprits for Xenia problems.

water change and keep low flow on them for a few days. Also how do you put the kalk in?

[theJiggyfly]

mix some iodine in a bottle and baste them like you are target feeding.
