Pulse coral question

I put in a new pulse coral about 3 days ago and on the face of it it looks very healthy. It grows very nicely during the day (lights on), and retracts during the night. The only problem is that it does not pulse. It is near the top of the tank in relatively good flow.
All water paramters are good as the rest of my corals and fish are doing very well. Any ideas?.

TIA

Pioneer

Xenia is very picky to what the surroundings are. It likes good flow, high PH (8.2 - 8.4) and light.

My xenia pulses like crazy, but it is 8 inches below 384 watts of light.

It retracts when the lights go out, and then comes back out after a short while ans pulses in the dark... I was told tht if it is pulsing in the dark, it is happy with it's habitat. When I take cuttings, it takes 4 to 5 days for it to start pulsing again..

This is my Xenia:

Thanks for the help, the xenia is near the top of the tank in good flow and about 10 inches from 300 watts of halide. During the day sometimes it is able to stretch so that it nearly touches the surface. The PH is 8.1 so I am at a loss.

Is it worth moving it?.

some people feel the iodine levels in the tank affect xenia pulsing.
You might want to test the iodine levels in the water.

Deleted one of the posts because it was doubled.

Yes I have read about the iodine levels also. I do not check for it, so, I cannot say one way or the other.

How were the conditions in the place of purchase? Was it under MH there? or under PC? The light spectum could be not as intense or too intense at the moment, and it is taking time to adjust. Try moving it a little lower for a day or so, and if that doesn't do it, move it closer. How is the calcium level in the tank? do you dose with 2 part or Kalk? I know, lots of questions, but more info is good...

Hey, Pioneer,
It's possible you have a different sp. of xenia than their particular one. I have a "pulsing" xenia at the top of my tank that sounds just like yours. I have had it for several months and it has done very well (I know have three growing!), and never really pulsed. It also looks a little different than pulsing that I see actually pulsing.
