Removing zoas

[HB AL]

Any way to remove these zoas from this rock? I tried Aiptasia x it didn't phase them. The rock is large so I can't take it out and scrub them off and power wash them off. I can wrap a good portion of them in some thick black plastic basically a localized black out, how long would I give that and do you think it will work? All ideas are welcome.

Man, those look cool, too bad you cant pull it and sell it or something.

Manual removal. Sometimes if you are lucky you can peel them up. Other times not.
Or you could try kalk paste, that might work.

You should try fragging them with a razor blade, you could really make some money. But if you have your heart set on killing them in the tank then I would imagine injecting them with either boiling water or hydrogen peroxide would do the trick. If you go the peroxide route just make sure not to overdo it in one session. The rule of thumb with peroxide that has become popular is 1ml per 10 gallons of water volume in your tank at one time.

I need to remove some too. I'll try to peel them off the rock but if I end up being aggressive and scraping and cutting them will palytoxin kill the tank? No way to remove the rock.

Probably not, unless they are the more toxic palys. Most zoas are pretty low in palytoxin. If you have a bunch do a little at a time or put in some carbon and you should be fine.
