Help ID long string-looking algae

[Pau Hana Reefer]

I can't seem to find anything like this in past threads or on Google.

I recently have been seeing a number of these in my tank. They grow quickly when other types of algae grows. They grow pretty long, and eventually break off. There are also a bunch of shorter ones in my tank. They are white and attach only to my sand and my rocks.

Anyone have any ideas or able to point me to some old threads to to help me ID this?

Probably a string from a vermited snail did you follow it back to where it is coming from. If it is a small weird looking tube than it's a vermited snail.

They all originate directly from the rock and sand, no tubes.

Try dosing vibrant and manual removal than. That gets rid of all my algae problems.

I second the vermetid snail

Likely feelers from scavenger worms But also similar to vermetid snail slime

Could be digitate hydroids, but hard to tell without a close up

Thanks for the feedback everyone.

So I looked into both vermetid snail slime and digitate hydroids and it doesn't look like either.

Regarding vermetid snails... Most pictures I found showed red-ish tubes. Can their tubes be white?

I've had one's with whiteish tubes with red bases in my tank.

Did you ever figure out what this was? I have the same thing in a newly cycled tank. So, it not likely worms or snails.
