Looks similar to a type of colonial hydroid. @KJ @Lovemyreef2015 #reefsquad

^^^^ I second colonial as well^^^^

What did you use to dip this with?

Fenbendazole from amazon. 2 scoops with a spoon from red sea test kit. it killed all the other hydroids in my system.

they are Hydroids no doubt

Does anybody know what will kill these guys? The fenbendazole doesn’t even phase this particular type.

I had good luck to squirt a mix of RODI water with MA (60-40) over them with a turkey blaster a few times.
Just a gentle squirt and turn all pumps off for 3/5 min.
Just keep a eye out on your Ph as it will lower it but will recover in a hour or so.

Btw, it works as well to kill all spores in a BA, just inject them with a syringe.

Ok, I have to ask... what is MA?

Muriatic acid??

With @Diesel that is a possibility!

Either that, or some brand of hot sauce!

Hot sauce, you might be onto something!

I'm not just saying.

You mean S&S sauce, hot sauce will raise your Po4.
Hydroids will also disappear slowly when you run ULNS.

the muriatic acid is not going to have an effect on my other corals in the area?

If you mix 4ml with 6ml RODI water and squirt gentle over the hydroids nothing can happen.
They will retract them self but the next day you will do it again.
Simple, easy, inexpensive and effective.

BA stands for Bubble Algae

Muriatic acid is Hydrochloric acid. It breaks down into salt water when neutralized in your tank so no negative long term impact. Just the temporary drop in pH and small drop in alkalinity.
