Help please: Control of spionid worms?

[polarcollision]

Reasonably sure these worms are spionid. 2 white filaments/tentacles that come out of a fragile tube made of sand and whatever ‘glue’ the worm makes. Filaments are about 1.5 - 2 inches extended

Any zoa it touches ends up melting away so they have to go. Plus, they’re taking over.

How do I control them?

I’ve tried a coral banded shrimp on recommendation, with no luck.

Thinking about Prazipro... pros/cons? Something else?

Worm out of tube:

Tube

these are ALL worm tubes. They’re out of control.

these seem as spionids, spionids do not have the ability to damage corals

I wish that were true. Every zoa eventually melts away when in contact with them.

they neither have stingers spines or toxic secretions

Will you please focus on my question; I need to know if PraziPro or something else will eradicate them.

i do not know of any chemical that will specifically kill spionid worms without destroying your tank

If your zoas are melting from contact with these, you either have a much more serious underlying tank problem or there is a different parasite/hitchhiker bothering your zoa. Spinoid worms, like all the ones you pictured are time and time again proven harmless. Whatever is happening to you zoas, it is extremely unlike the spinoid worms in your tank are responsible. Likely, they are benefitting your corals by being and active part of you C.U.C. and tank microfauna.
