Tiny lines in my tank?

[mattscheck4]

My tank is currently cycling with live rock. I have the brown algae bloom in full effect right now (not crazy about it, but I know it's just what'll happen). This morning I woke up to find lots of tiny line-looking things in the tank. Any idea what they are? Are they good/bad? Any help would be great. Thanks!

The brown stull is most likely diatoms. They will go away but I`m having a hard time seeing the lines.

are you talking about the "drag marks" that are in the sand? probably a snail, i have a snail in my fw tank that does that

Sorry; I've attached photos highlighting the tiny things I was talking about. I let them be today because I haven't heard anything about them being bad yet. They were still there when I got home tonight, but it seemed like there were at least a few less than this morning. Again, thanks for your help. : )

Heaven help us! Someone pull out the electron microscope! lol jokes. They might be tiny worms but since they haven't moved I doubt it. Other than that I have no idea.

They could be Bacteria from the Live rock but also could be tiny worms... I would not worry too much about it just yet unless it gets out of hand...
