HELP!!! What is it?

[CTS]

I have these things in my tank on my powerhead and on my intake filter (picture). They look like little slug type things. Are they good or bad? Sorry for the bad picture I will post a better one if needed. Thanks in advance!!!

The picture is too blurry to help me much. There's an id page at www.melevsreef.com that might help you.

The picture is too blurry to make out really.

Possibly tunicates?

They look like small sycon sponges to me.
