Bubble Algae on Star polyps

[theclemsonkid]

SO I noticed today that on my green star polyps there are two small green algae bubbles. Is this something that I should try and take care of? Or is this something that will take care of itself?
Thanks for any answers!

Are you sure it's bubble algea and not caulerpa?

tweezers and knock it loose if its bubble algae.
that or just leave it alone and let nature worry about it.
