Coral ID needed

[650-IS350]

Coral ID on this potential pest.
Having an infestation of this type soft coral, brown colored looking sympodium type. But grown and infest like GSP. They can take a nuke of kalk paste and come back within a couple weeks. They sprout all over the rocks like Aiptasia would.

not my picture but someone else who has the same issue.

Wow I don't know the ID on those but they're pretty awful. I finally got rid of some that came in on a frag by picking up hypodermic syringes then directly injecting them with boiling hot vinegar. Got some weird looks from the pharmacist at Walgreen's

Found some more of the same type coral here in RC.

I want to say a type of colonial hydroid, but it's just a guess. I really don't think its a soft coral because there's no mat, and it's clearly not a leather so....

turned off all the pumps last night and nuked all I could find in the tank, let it settle on the rocks for 30mins or more then turned back all pumps. I'll see later after work when the lights are back on if the scourge comes back.

I dont think thoses are hydroids because the tentacles have pinnules. hydroid tentacles are usually straight and smooth.

95% nuked, will re-do nuke again this weekend to see if new stragglers pop up.
