My Xenia won't pulse - perhaps a solution?

I often see people post this issue on the boards.
They have Xenia, usually the all white pom-pom type, and it isn't pulsing.
The first responders usually recommend checking alk, and if low supplementing accordingly (use baking soda or washing soda solutions).
Uncommonly, the original poster will respond saying the alk levels are good, but still the Xenia won't pulse.

That'll get other suggestions like check the magnesium, check iodine, etc.

I was in this boat for weeks. I also noticed my anemones were looking feeble. Just weren't blossoming like I expected. Oh, and not only was my Xenia not pulsing, but it was looking shrunken as well. Not a temperature issue, Mr. Costanza.
I'd do water changes to check try to reduce nutrients (not that I had nutrient issues), but that didn't work. Still no pulsing Xenia.

Although my salinity according to my refractometer was reading approximately 32 ppt (or a specific gravity of 1.024), I thought it might be low.
At the next water change, I decided to go heavier on the salt and see how the tank reacted.
To get to the point, low-ish salinity appeared to be my problem. Now that I've upped the salinity, the Xenia is pulsing well.
I haven't made any other changes. Perhaps lower salinity lead to Xenia dysfunction? Anemones are looking better too. More blossomed. Instant Ocean: Reef Viagra (copyright Moe_K 2014).
 
Our Rainbow BTA is the most sensitive to water quality in our tank. He is the first one to show immediate signs of unhappiness if temp, salinity, alkalinity, or anything fluctuates. Our pulsing Xenia are most unhappy during water changes, perhaps due to swings in parameters between removing water and adding the new.

If the BTA isn't out within an hour of lights on or hides during the day I know something is up.

BTA? Sorry I'm new I'm just trying to learn as much as I can. What does that mean?
 
Bubble Tip [Sea] Anemone. The Xenia and the Anomone were the first to signal water quality issues for the OP and for me as well.
 
I read somewhere that the red sea salinity is 35ppt (1.027) which is what I shoot for in a reef. Xenia has always been a great "visual aid" in telling you if your water quality is up to snuff. The usual problem is that it flourishes and takes over the tank.

I agree.
