I have noticed, for months now, that I have a lot of these tiny white threadlike filaments sticking out of the sand and liverock. Actually, I haven't noticed them on the liverock since I did the peroxide soak a couple weeks ago. I'm wondering what these are and if they are problematic or beneficial. They don't seem to be an issue for any of the corals, fish, or inverts. I'm more just curious for the sake of knowledge what they are.
Thanks in advance.
