Need ID

[jsburk0]

Attached is a picture of something I need an ID on. I think they may be hydroids. They are small white tubular creatures about a quarter of an inch long. Can someone ID and tell me if they are a problem and if they are how to get rid of them.

I was researching some more on these creatures and found some pictures that look somewhat like them. Are q-tip sponges a type of syconoid sponge?
