Cobweb type stuff on live rock?

    I have a freshly cycled tank with live rock. One of the pieces of live rock was only out of water for 10 minutes, and it's definitely got the most growth of stuff on it. One thing I have been noticing are these really fine white threads coming off the rock into either the sand or other pieces of rock. It's not tube worms- I know what those look like. If it was on land, it would look like the beginning of a spider web. I can't take a useable picture since I don't have lights on the tank yet (I'm getting them in the next week or so).

    Any ideas?

    Probably a Vermetid worm. Usually harmless unless it's next to coral then it can bug it. I had to kill one not to long ago by plugging it's hole with epoxy because as it grew and as it extended it's cobwebs it irritated the coral it was living next to/under. So typicall harmless unless it starts to bother coral.
