hydroids ...

So I thought I got rid of hydroids a while ago and I have noticed they are popping up on every piece of rock I have in my tank now. In the past I have just taken the rock out and put epoxy on them. I must have missed a small colony of them some where or the epoxy just didn't work. My only thought on how to get rid of these suckers for good is to nuke all of my live rock.

If I nuke all of the live rock I wont be able to put it back in the system until its completely cycled again. Will this effect the bioload from the fish and coral in the tank since they will be without all of the live rock for so long?

I also have a Diamond Goby, removing the rock will take away his burrows, will I have to put something else in there for him to burrow under?
I have a piece of slate rock in another tank, would this be ok to use?

Do I need to nuke the sand too and start over with new salt water?

Is there an alternative to nuking the live rock that will kill the hydroids so I don't have to remove all of the rock and kill all of the other stuff living on the rocks?

I'm really not sure which route I should take with handling this and could really use some help or a plan of action. Any help is appreciated & Thanks in advance!

Yes it will definitely put a huge dent in your tank bio filtration. It could take a month or more for bacteria to fully recolonize. You will have to keep a close eye on your water parameters during this time and may have to do more frequent water changes.

Yes, I would give him a safe place to burrow. The slate rock should be just fine. When you put your rock back in use it as base rock.

 

My peppermint shrimp have wiped out my hydroid population in my DT. I still have thousands of hydroids in my sump and a smaller connected tank but none in my DT.

 

I have had a few outbreaks of these and never did anything and they go away..... In time. I have seen them probally 3-4 times to the point I was cleaning the glass many times a day. The eventally starve to death so they will pass.

 

Yea I have a peppermint shrimp... he is banned from this tank due to the fact he doesn't eat aiptasia and likes to rip apart my Xenia. These aren't the type of little white hydroids that stick on the glass, I did have those a while ago. These are the ones that resemble very small brown zoas I guess, not sure what to call them exactly. I should have clarified that in my first post. I don't have any in my sump, but I do have a TON of pineapple sponges in the sump and not in the DT lol. I'm just dreading nuking all of the rock considering there is so much life on all of it that I would be killing along with the hydroids.

 

Did your peppermint shrimp eat the white ones that stick to the glass or the brown hydroids that grow all over the rocks? I have the brown ones that grow on the rocks, just wondering incase I should try this out with my peppermint shrimp. I would have to move my xenia to another tank so he doesn't tear that apart again lol.

 

They have eaten both types, the little brown ones and the small white ones.

 

Hydroids the devils spawn...

Yea I just found out that those hanging worm looking things were hydroids...yea have quite a few small ones on one rock with a few larger ones any advice on killing them??

 

Manual removal or try some peppermint shrimp.
