Black spots on Xenia

[Texas Reefer]

What causes black spots on Xenia?

 

[Texas Reefer]

Anybody see the tiny black spots on the stalk to the right, just left of the snail crawling on the overflow?

Barely. I wouldn't worry. Does your Xenia pulse?

 

[Texas Reefer]

It occasionally will close a hand. It seems healthy, is splitting. Has had these spots for a month. Someone told me it would pulse more if I added pH buffer.

Adding pH buffer can be dangerous to a reef. It can spike your alkalinty.

Your Xenia may never pulse or might not even be Xenia. It may be Cespitularia.

It was cut from one that pulsed.

Just give it time and good water quality and it should do fine for you. :)
