Can anyone ID this

[kb reef relief]

I have these white filaments all over the tank. Also have a vermetid outbreak that I am treating with bumblebee snails and manual removal. Alk is 10.5, salinity 1.025, phosphates, nitrates and pH are I
in normal limits. Any help is greatly appreciated!

My best guess would be a hydroid.. but that’s just a guess cause I’m not sure haha… colonial hydroids almost look like mini polyps.. then there’s the type similar to that but hair thin..
