ZOA Disease

[thomas.vette11]

Good Afternoon,

Unfortunately one of my zoa colonies has developed a greenish tint and they’re starting to die. Does anyone have advice regarding how they can be saved?

I’ve tried both Iodine & freshwater dip 1 week apart. They’re still closed and turning darker. It’s pretty sad, this was my first colony and they have been growing 1.5 years

Salinity: 1.026
Alkalinity: 11.5
Ph: 8.1
Ammonia: .15
Phosphate: 0
Nitrate/Nitrite: 0
Calcium: 450
Magnesium: 1200

Thank you in advance.

Zoes luv them some N03 and a bit of P04. 0 is not good in my book.

A lot of soft corals don't do well in presence of ammonia. I'd get that fixed first before dipping and doing anything else. Something in your tank has changed and there is ammonia present.

Not too sure about that statement. I and many others dose ammonia for our corals. For OP undetectable phosphate and nitrate seems to be an environment where dinos thrive and could be what growing on your zoas irritating them.

There is nothing wrong with dosing ammonia if it's being broken down quickly. If your dosing ammonia for your corals, your probably after the end product nitrate and not ammonia itself.

Ammonia that is constantly detected though, that's going to burn soft tissues if not dealt with. More sensitive species of corals will close up in prolonged exposure.
