spirobid worm

I noticed my tank had these little white specs over my glass. It's a little bigger than copepods but not sure what to do? Can anyone help me!

I found a tube worm growing on a snail shell so that's interesting. I have had a recent brown hair algae outbreak and I am wondering if it will pass or what I have to do about it. I have a spirobid worm outbreak does anybody know how to take care of them?
