Ruffled Palys...why?

Any chance your carbon is exhausted?

Perhaps a neighboring coraL???

I could test the tank I suppose. The Zoa tank get water from the reef instead of fresh saltwater, so the values are good and the water is pristine and aged well. The unIDed Paly was ruffled in the reef though, and the alkalinity has always been in check. Alkalinity in the reef is 8-9 dKH.

I haven't used carbon in the Zoa tank, but I do use it in the reef, and the Palys were ruffled in the reef. I just boiled some fresh carbon for the Zoa tank. I will add it to the mini sump tomorrow after it is done soaking. It will just run passively in a bag. I should hook up a reactor for carbon and GFO...

Just Zoas and Palys nearby. The only other corals in the tank are 2 Ricordea florida, and a small colony of various Euphyllia (Hammers and Frogspawns) that aren't touching any of the Zoas or Palys.

I experienced something similar when I changed to a higher output bulb. My paly's have not opened fully since changing bulbs so I assume they do not like too much light.

Lighting is a Hagen Glo 2x24w T5HO with an UVL 454 and an AquaScience 15,000K. Both of the Palys are on the sand which is about 14" from the bulbs. I tried switching bulbs; at one point I had the UVL 454 with an UVL Super Actinic. Despite the shockingly blue look to my eyes (and decreased PAR), none of the corals had a reaction. The tank ran that way for 6 weeks. I also tried a 10,000K bulb (can't remember brand) with the UVL Super Actinic and the corals didn't react to that either.

FWIW, the LFS here has a large, wicked colony of Nuclear Greens about 24" away from 3x400w XM 20,000K halides w/ T5 supplementals as well.
