Colonial Hydroids....help please!

[Crystal03JC]

So, no idea where they came from but we have them on a decent sized rock, our 1 Duncan coral & on our powerheads. As of now, that's the only place we see them. What can we do that absolutely will get rid of them? I read that even if there is one left it can repopulate the tank again.

We have a 90 gal tank full of rock and coral everywhere, it would be terrible to sit and watch it all die everyday.

Do you feed any coral foods like Reef Chilli or Coral Frenzy?

Get some epoxy or kalk paste and cover them with it.

No we don't, we just feed mysis/brine mixed blocks

It won't make them come back?

I'm having the exact same issue. There are thousands of them in my tank. I have heard from the seahorse forums that there is essentially no way to get them out totally, just beat them down by not feeding as much as possible. I don't know what I'm going to do. There is no way I can cover them in epoxy or kalk paste. They are all over the undersides of my rock. Its just not possible. Maybe someone will have a better idea or suggestion.

I've got the same problem Dolmo5000. They're all on the undersides of my rocks. Do they look like this?

I too am a victim of hydroids. Such pesky snot boogers!!! I have been using a toothbrush to scrub them off places I can get to. Mine have also infiltrated the sand bed and I use my siphon to try and bury them and I pull out chunks. I am praying the copperband I have in QT will help when he is ready. I feel your pain guys, I do.

following for knowledge. wish i had an answer, hope someone here does

 

[Dolmo5000]

Danyboy402, yes, mine look exactly like that. They will kill zoas if unchecked for a week or more. Not stinging to death, just keeping the zoa closed till starvation. I used to feed and love reef chili and phyto, which probably explains why im in this predicament to some degree, but i stopped about 2 weeks ago. I do have a coco worm that i guess ill have to target feed. Peppermint Patty is over 2 years old and i cant loose her over these stupid things. Squishie89, ive read a few places that scrubbing them like that does no good, just spreads them. That said, ive been visualizing some type of small scrubber with a syphon attached to get the scraps out of the system. Put a filter sock in the sump, start a siphon and collect all the dead bodies! I hope to try this specifically for the hydroids in the next few days. Ive done the sump filter sock several times with great success.

Yikes so we're all in the same boat! We are going to take the rock out today and scrub it, rinse it in rodi water and put it back in. Throwing the Duncan coral out too :-(

Take out the major rocks that are covered and dispose of them. Clean your power heads in ro/di and scrub all parts. Any small areas of colonial hydroids cover in epoxy.

Yeah most likely, but at least it inhibits the spreading.

I wish I could do that, but that would mean a whole tank revamp. The fake reef that is the centerpiece is infected. Not to mention my sand bed is infected.
