Help I.D small white strands.

[jvann23]

Looking for help trying to I.D this small white strands in tank. Showed up after water change, detritus worms?

Probably just filamentous algae covered in white detritus kicked up during the water change. Could also be digitate hydroids if they retract when disturbed, but doesn't quite look like it from the photo.
