Seriouse help needed. Pest I have not seen in 25 years of reefing. (With Microscope pics)

[CC24KCORALCRUZE]

So I have been battling something in my tank that I have not seen in 25 years of reefing. It looked to me like detritus at first but I am now unsure. Whatever it is seems to be burrowing or making tunnels using detritus. It can be fairly easily cleaned but comes right back. I would like to eradicate it. Please help ID and help me get rid of it.

The next few shots are using a microscope to help ID it.

In this section I see these curlycue appendages

Here I find a worm of some kind

Any still pics under white lighting?
I see what may be a flatworm, detritus worm and ostrapod

Anyone have any idea what those curly cue things are?

Anyone have any idea what those curly cue things are?

May be epitoke worms

Looks like those tiny shrimp that make tunnels. Not sure how to remove them though. Think I’ve I got a couple as well. No clue what the wormy stuff is.
