Anyone who has even seen this on their zoas please chime in!
This started out with just some of my zoas being infected, but seems to be spreading to all. They turn darker...even kind of blackish with a while/opaque film over them. They seem to shrink up and eventually dissapear. In the photo below the whitish film can be clearly seen particularly in the middle. These are eagle eye zoas...so as you also see the red has turned to almost black.
I cannot remove this rock without disturbing the entire tank....this is to do my aquascape and a pesky center brace. I have done peroxide dips on the frags that are removeable. This had no noticeable affect and no evidence of pests. I did have one extremely tiny red dot that I found with a magnifying glass....but certainly one tiny tiny bug on 1 frag shouldn't be enough to kill? This leads me to believe this is bacterial or fungal.
Can anyone PLEASE offer recommendations. At this point I pretty much think my best bet is to try and save the frags....but the problem is that whatever is happening is contagious. So until the zoas on the rock die I will need to continue dipping and dipping the frags.
Other information....recent changes :
-starting 2 part dosing...over the past 3.5 weeks the alk has been moved from 7 to 8.1(on purpose).
-changed carbon from Rowacarbon to BRS Rox
Water Parameters:
SG - 1.025
Ca - 420ppm
Alk - 8.1
Phos - .02
Nitrates - 0
Mag - 1300
