Options for Hydroid removal?

[Layne.Wilson]

I have small hydroids on a new frag in my quarantine tank that I would like to remove. I would like to avoid the nuclear option of adding Fenbendazole to the tank since it doesn't make sense to kill or severely stress all my coral over one frag that has hydroids on them.

I have tried hydrogen peroxide at max dosage for 10 minutes for three days in a row, and it had absolutely no effect on the hydroids on the zoa frag.
I also softly scrubbed the frag with a toothbrush after each peroxide bath.

I don't want to throw out the zoa since it was a pretty expensive frag.
Are there any other options?

What do you consider max dose?

I’ve done a few 100% h2o2 baths with 3% h2o2 and have been fine with zoas (burnt a candy cane though)

I put it in a cup of 3% for 10 minutes three times

Oh okay I am of no help then sorry
