how to get rid of them

I have 6 years old 125 reef tank. Many different corals and6 fishes. I see that one kind of Zoas taking my tank over. They really not pretty, the. y all over tank. How to get rid of them. Take rocks out and let it dry? Is that the only solution? Thanks

 

If you don't like them, why don't you try to find someone to buy them from you. I would imagine if you posted an add on craigslist that you would make somebody happy.

 

They cover at least 5 rocks with other coral on them. Sure thing I would give them away if I could.

 

What do they look like? Do you have pics? In my experience different corals change color under different lighting.

 

You can usually grab them with tweazers pull. They tend to pull up together in a big mat. Using some kalk paste to finish them off can help too. Be very careful though, they can release a toxin called palytoxin. This can kill you, your pets etc... very powerful stuff. I wouldn't let them dry out, as you suggested in your first post. If they turn to dust, and the dust gets blown around, or on your hands and you touch your eye or mouth or something, you can get poisoned. Or can get poisoned if you breath it in. Also, definitely do not put it in a microwave or try to boil the rock, or anything like that. The steam can be poisonous. I'd wear gloves, eye protection and a dust mask when working on them. If you work on them in your tank, run a lot of GAC.

 

I would like to add that palytoxin attacks your respiratory system. Some people are more sensitive than others, so be very careful.

 

Wow, that is some great info. I didn't even realize all of that. I guess in need to invest in some gloves to wear when working the aquarium.

 

It is also a good practice to wear disposable gloves and eye protection when fragging all corals. It helps protect you and the coral itself. Washing your hands afterwards is also a good idea.
