Zoa dip on hydroids

Big E · Jul 31, 2013

Will any of the zoa dips kill hydroids. They aren't the colonial hydroids........these are small and clear....you can't even see them without using a magnifying glass. They are in between polyps on the rock/plug and cause the zoas to close. They look similar these----

I'm thinking hydroden peroxide would be my best bet? I also have Tropic Marin Pro coral cure and Bayer Insecticide.

I'd hate to have to superglue them as they are impossible to see when the frag is out of the water. I'd have glue the whole area on the surrounding zoas and probably mess them up.

Try to rip them. I've never tried to dip because I see them after the coral is glued to a rock.

hydroden peroxide should work just water it down I usually dump my zoas in hydroden peroxide if I see unwanted stuff on my frags

It would be impossible to rip them out. They are tiny and clear and in between slivers of gaps in the zoas. I won't be able to even see them when I take the plug out.

On the peroxide..........what's the highest level I can do? More than a 50/50 to water mix? How long in minutes should I dip?

I ended up doing the peroxide 50-50 dip between 4-5 minutes. It seemed kinda harsh, but I wanted those hydroids dead. I can't see them now and I saw a few zoa heads popping up the next day. I'll try to remember to update for future reference.
