Spider Webs?

[DebbieLama]

Hi. A couple of weeks ago, I noticed some thin, white, spider web-like strings on my macro-algae. I didn't think too much about it, except to wonder where it came from. Now I have some of the same thing on another rock area.

Does anyone know what it is and is it ok? Thanks! :spin2:

I was about to post exactly the same thing. Mine seem to be coming out of a new polyp sprout, not sure. If you try to remove some from tank it is so fine there is nothing to look at.

Hi. They are almost like hairs, so thin.
