Got Hydroids?

[Robert Patterso]

I do and not sure what to do about it. Are there any natural methods of killing these things off. Or chemical? Never had them, don't know where they came from. From what I understand their not a good thing

The hydroids I got in my tank came around the 6th month mark if I recall. I had them COVERING my glass...front, sides, everywhere. I would scrape them off the glass with my algae cleaner and I think they just came back in bigger numbers (parts grew into individuals??). Anyway, just like all of the posts I read, they disappeared after a few weeks. I haven't seen them since. They did last a while though...and I felt my population was pretty large...but they did go away eventually on their own.

Now I have a huge population of pineapple sponges in my overflows and in my sump....they have been around for a while now too. I don't think they are bad...but I get a little tired of looking at the sheer numbers of them.
I think with a lot of this stuff, it is just natural cycles of stuff.

i had the brown hydrioids, given to me from my lfs.....anyway, they were really SLOW growers but after a time they did start to spread. i would take the rock out and scrub and scrub for them only to come back. how i got rid of mine was really by accident....i had the rock in my 75g and had taken all the rock out b/c i was totally redoing my tank. i had filled all my rocks in 4 of those 5g buckets. i had the rocks in there, with no lights on them, no thermometer, no air pump....nothing for a good three days (only b/c it took me three days to re-do the tank). anyway, i put the rocks back in & one year later haven't seen them back. the lack of air flow/light/movement/temp killed them off. lucky me!
really, though, if i were to get them again i would just take out the rock they were on and do the exact same thing. no need to take all rocks out just the rocks the hydroids are on.

I had hydroids in my reef tank a year or two ago, and I wasn't having much luck getting rid of them. When I did searches on how to eradicate them most people said they would just go away naturally. Well, it took a while but that's exactly what happened.

 

[Robert Patterso]

So far from what I have read there is no real good way to get rid of them. Googled em and most everything was 3-5 year old post. Guess I will wait and see. Taking the rock out really isn't an option at this point. Yet

I've had the brown tube-worm-like ones before (and still have them now, but keep them in check in my 24G nano). I've taken out rocks and cleaned them off with a propane torch so that they were pure white -- only to have them recover in 1 month. I've dried out rocks for 2 months -- only to have them grow back. I made the mistake of thinking they were tube worms when I first got into this hobby and fed them live phytoplankton. They grow fast in a high-nutrient tank.

Only way I keep them in check now (without tossing the rock) is to scrape or break off the area where they are attached and them cover that area in a thick kalk paste. And sometimes that doesn't work. I am about to pull out the one rock where I have them on it now and torch the things followed by kalk. If that doesn't work, I'll try a blob of super glue gel. I really hate hydroids. Those who have had them "just go away" never had this version of them.

Only natural fix I found was to put galaxea upstream from them and let their sweepers do their thing, but that only cleared out a hole in the middle of them.

If you get the strain of hydroids I had, they will be a thorn in your side for a long, long time. I eventually broke down my tank because I got tired of fighting both them and the razor calurpa I let get into the main tank.

I had a ton of them the first few months my tank was set up, then they started to disapear, I dont see them at all anymore.

Unfortunately I have the little tube hydroids and they are definately the devil. I plan on putting some reef poxy on them and entomb them.

I covered mine up with epoxy. Haven't seen them since.

The pink epoxy blends well with the coraline on the rocks.
