Thank you.
It is bone white, moves with flow a bit. I have removed the blues and added another two images, the second is a different one I have noticed?

I must add that my tank is just clearing after the live sand so there is a bit of silt/sand that has settled on the rocks so it may not naturally be as white as it seems?

Thank you. Is there anything in particular I should be looking for that should ring alarm bells?

Some sponges have been known to smother corals over time, but being that your tank is new you should be ok for now. When you start adding corals to the tank then you'll need to watch out. One good thing about sponges though is they can be real easy to "thin out" so to say. The ones you have look like they would be real easy to manage.
On the second thought, I cannot completely disagree on the identification. Thought the tank has been running without fish for last 2-3 months but do feed my corals occasionally and can see bristleworms thriving.
I'm a bit worried at this point as there are at least 5-6 such worms that I can find with only red lights on and expect a lot more to be hiding. The largest I can see is hardly 2 inch long and around 1mm thick, probably the only way to catch them would be something like a planaria trap that we use in Freshwater tanks.
Here's a recent pic, probably this will help in positive identification.

So i'm not sure what that worm is, but Fulgida worms don't have antenna on their heads.
That looks like a eunice worm (not the bobbit in particular, but likely a predator if it has antenna)
I'd remove that sucker as well. Scallops in a PVC pipe with pantyhose works pretty well for Fulgida worms, might work for other predatory worms as well, but you might need to cycle through bait types until you find what it likes.

That's cool, I had no idea there was a 'bristleworm' (this guy) and the 'common bristleworm' (the ones I've seen before)
There are so many critters in this hobby it's mind blowing.
Does your worm eat like this one?

Thanks for all your input guys, especially alcimedea and ALSimmons.It's a relief that this isn't one of the" not so wanted type of worm".

These just showed up on the glass the last 2 weeks or so. They are small but spreading relatively quickly. They move, so I thought they might be pods at first, but they only move with the water flow, they are attached. I know the pictures aren't great but it's the best my phone could do.

If that is indeed what they are I wouldn't worry about them too much. (harmless filter feeders) Being that they are on the glass though they should be real easy to remove with a Mag-Float or something similar. Just do this right before your next water change though.
