Blackout to Kill Unwanted Zoas

[KenO]

Whenever I want to slow down the spreading of some palys and zoas, I simply use Tunze Coral Gum. Just create flat pancakes, press them on top of zoas, does the job.

Does it stick to the zoas? Won't they just grow over the top of the epoxy?

Google class 3 laser. That’s what you want.

Here is a good one that I got. Comes with reddish brown glasses that make your tank look good. 59.99 two day prime ship

Looks exactly like the one I got from Amazon.

I put my rock with zoas on them in a bucket with no lights for 2 months and when I put the rock back into my new set up the zoas were still alive.

wow that's pretty amazeballs

If you take the rock out, the sponges might die. I’ve read that they’ll do that when exposed to air.

Also, I lost a zoa frag that got knocked in the sand face down for 2 months. When I finally retrieved it, the polyps opened up about a week later. These weren’t designer zoas but some of the nicer type. Blackout won’t work as others suggested. Now everyone has got me wanting a laser. ;Facepalm

i have the same, although mine aren't even blue they're just ugly brown. i tried covering some of them on a rock with another rock and that did nothing, they just grew onto that rock and up the back wall.

i got all garbed up to do some cleaning of that top rock, managed to get squirted in the face by the zoas, put the rock back in the tank and that same day they were reappearing

my next solution is to take the original rock they came on out of the tank and just break off the pieces that have the zoas on them. probably won't get rid of them completely, but doubt that eradicates them. they really suck

they're in such a prime spot too

Those look like palythoas. Be careful because those look like the type that contain palytoxin. If you move them, cut them, irritate them, they can release toxins into the water.

yeah i did accidentally cut one in the tank, but i'm not going to risk my fish by hacking away at them in the tank. and they seem to be quite resistant to even a razorblade cleaning, hence my hammer and chisel plan

 

[Stigigemla]

I would never dare to use hammer and chisel against Palythoa. They are much to poisonous for that. There are numerous threads here about Palytoxin poisoning. And if drops dry they can poison You a year later.
There is a person here on R2R that got poisoned grom cleaning rocks that had been lying dry for a Year.
I only know 1 safe way to take them away. Thats bleach. 1 part bleach and 10 parts water cleans off every sign of life from the rocks. But you need to rinse the stones very careful before putting them back in the tank.

Only use a laser when You are alone in the room and having the special protective glasses on. And active carbon in the tank. Active carbon takes up the poison.

Where did you read that there can be paly toxin present after a year ?

 

[Stigigemla]

It was one of the Palytoxin threads here on R2R. Sorry but I dont know which one.
Maybe someone reading this can say?

 

[scriptmonkey]

I am pro 300 Blackout usage to kill the Zoa. Better aim well.

hmm, i'm not going to hammer and chisel the palys themselves, i was just going to break off the part of the rock they're on. if i have to remove the rock and bleach it, then it's not going back in my tank as is

dang these things, you make it sound like i should call hazmat or something lol. i was just going to break off the rock and then toss the rock far away from my house

Although I’ve never heard of a reefer perishing from these, many have been hospitalized with severe symptoms. Take proper precautions when dealing with these. You could very well keep them in your tank as many do. Just be aware of said dangers.

yeah i do, gloves mask and eye protection for sure. my lfs claims he got sick after messing with zoas so i don't doubt their toxicity.

i'm just failing to understand why i shouldn't break off the piece of rock they're on. i don't see how else you can get rid of them short of bleaching the rock, which i don't want to do

I have also used high powered lasers to remove pests. If you do buy one be sure to get proper safety glasses. The ones that come in the kit are often cheaply made and offer little to no protection from the beam. Decent glasses will range from $50-$100+. These things are no joke and are especially dangerous around glass as it can reflect back into your eye.
Even a small beam making contact with your eye for a fraction of a second will cause irreparable eye damage. Even just looking at the dot on a wall can cause eye damage.

You can break them off of the rocks as long as you have the proper safety equipment which it seems you do. It also doesn’t hurt to let others in the house know what you are doing/working with. That way if anything happens they can call for help and let the ‘help’ know what caused it.

Mix up some kalk paste and use a syringe and coat them with it. It will kill them.
