Best way to kill pest Zoa/Paly?

[chaostactics]

I swear I had a thread on this already...

Interested in hearing people's successful* methods of killing Zoa and Paly without removing rock nor the zoa/paly from the tank.

Also if you're killing more than a couple of polyps do you find that water changes, carbon, other methods of toxin export are crucial?

If you're killing Zoa/paly adjacent to others do you change your methods?

*successful being things like: Effective in killing off polyps, doesn't result in a huge mess, repeatable etc.

Step one: figure out if you have a toxic species or not. Most zoas aren't notably toxic. It's generally palys that are the nasty ones. If it's not a toxic species, there's no need for any special precautions.

put a torch or nem next to them.
i don't get how you're killing them and not removing them?

I think "removing from the tank", in this context, means physically taking the coral out of the tank in order to do things to it.

Step 1 make up a fancy name for it
Step 2 try selling for a lot of money
It should then die

Precautions re: carbon, water changes, etc?

Unfortunately do t have any of those laying around in my fish junk closet

^this is correct. Cannot remove the rock as it's structural and epoxied.

Use hemostats to remove polyps or is that breaking the rules?

 

[chaostactics]

So far I'm thinking about boiling tap water to keep the chemistry more or less consistent and injecting a couple a day or a few a week.

I'm also considering F aptasia but it's really hard to use on a vertical face.

You have been doing this long enough. Have you seen this method yet? 1/4" stainless steel stray inside 1/2" hose, you should be able to suck out the polyps without poisoning the water. Works great for me and no chemicals needed.

I don't know that you're going to get rid of them that way, though. You can pull 'em off, sure, but the remaining tissue will regrow.

It may or may not, it is one way to control them, with the steel straw you may be able to scrape off all the flesh and suck it out.

that's how i read it. how do you get rid of them with out removing "them" which is how it reads.

OP, just to clarify: you mean methods that don't involve removing the rock, or whatever else the zoa/paly is on, right? Not methods that somehow kill the corals while leaving them completely in the tank?

I slapped a torch coral next to mine to control the growth. It does nothing. My torch is a wimp. Only thing I’ve found that keeps them under control growth wise is a ring of vermitids snails I tolerate arpund the colony.

I'll preface this by saying that I do not keep actual palythoa grandis, just "zoas".

- use a scalpel and thumb forceps to peel them from the rocks. Expect regrowth and repeating the process.
- use concentrated lye solution and a 3 cc needle and syringe. No need to inject just slowly squirt it on the location. A white film/crust will form covering the target. I pause the tank flow for about 10 min. (wear eye protection and keep out of reach of children)

I want to kill the polyps- without removing the rock from the tank.

I like this method. May be pretty high up on my approaches. Will combine this with some sort of chemical treatments after

I'm sure you may have figured it out, misspelled straw.
