brown hydroids, need help!

How do you get rid of them when pulling the rock is not an option?

 

[NicoleC]

Turn off the pumps and coat with kalk paste. Depending on how many you have and the size of your tank, you may not want to do them all at once.

I have read that with aiptasia you can touch a stinging coral to it and they will die off. Hey it came from the internet so it must be true, . I am not really sure if that method works or if it will work in your case, from what I have read they are close in the family. Just an idea.

I am tagging along as I have the same problem. Hoping someone has the solution!

We have killed some of ours with boiling water. They do die back but you have to stay on it. Also I have read where some nudi's will eat them.

cover them with reef putty

 

[simplereefer]

Thanks for the information. I am trying the kalk paste I'll let ya know the results.

 

[ReefingMadness]

My emerald crab takes care of them. Though I am trying to get it out of my tank. There is another thread on that though.

 

[simplereefer]

Applied the kalk paste last night. About 3/4 of them melted away.
I'm going to reapply Sunday. I'll let ya'll know the out come.

 

[NicoleC]

Good! You may have to repeat every now and then for a while. (Or for a long time.) It's like weeding... there's always some you don't find and then they spread. Plus some are not yet settled into the brown tubes you see.

Hydroids defeated for now. Kalk paste works well.

Peppermint shrimp.

 

[r2odie]

I have peppermint shrimps and emerald crabs and they don't touch them.

 

[simplereefer]

I have tried boiling water in a syringe, emerald crab, joe's juice
and none of that worked. The kalk paste in a syringe worked for me. I mixed up 1tsp of kalk to 1/2 oz of water. Turned the pumps off and applied waited about 5 minutes and started the pumps back up. Thanks to NicoleC for the info on the kalk paste.

 

[NicoleC]

You're welcome. There are very few things kalk paste won't kill.

You've been warned!

 

[rissaroo]

is there such a thing as adding too much kalk paste? I have alot of this stuff.....

 

[rissaroo]

If there are these hydroids on corals what would i need to do?

 

[rissaroo]

is a water change due afterwards or what....how long before I could do it again?

 

[NicoleC]

Yes, there is such a thing as too much kalk. It raises alkalinity. Also, if it gets blown around the tank it will burn whatever it touches. If you use a LOT of it, yes, you might need to do a water change but otherwise it's not dangerous. I would just avoid using a lot of it.

For hydroids on corals (are you SURE they are hydroids?), you will probably have to manually remove with tweezers.

anything acidic like lemon juice vinigar heat it up real hot i put it in a syringe from one of the test kits get it right over it close to it blast it they are history
