Need advise for unknown cloves

[ericmz]

I have these cloves like polyps growing on my live rock, don't seems to be doing any harm but it is spreading fast over my live rock. Can anyone help ID it and the possible way to remove it. Thanks & have a happy holiday!

Looks like bryopsis (an algae).

High magnesium using liquid mg additives from brands like Kent Marine or Continuum Aquatics can remove it.

Hi bro, don't think it is bryopsis. This one here do retract when disturbed. Thanks for your reply.

I had a similar problem a while back. I removed them using hydrogen peroxide as they grew too fast.
