I had a few questions about zoa pox. The other day, I noticed white spots on several polyps of Zoanthids. There are several different kinds on the same rock and it seems this one type is particularly susceptible. In any case, I looked online and from pictures I've seen it looks like zoa pox.
I've also read that people have dipped their colonies in solution with Furan-2 and had some success getting rid of it. I would like to take it out before it gets widespread.
Does anyone have experience with this? Anyone have clues as to what might have brought it on? (most of the things i've read seem to suggest no one is really sure why it happens) All of the corals in the tank are doing well, growing and expanding and I've had no real other issues with anything else.
Water parameters are:
Nitrates 5ppm (it's been 5ppm maximum and lowers to about 2ppm after water changes for the last 2 months)
Phosphate is 0 or near (need to get the salifert test, however)
Alkalinity is about 12
Also, I've noticed white spots on my coralline algae. I'm not sure if that's related. I assumed it was the snails and such munching on it that would cause the spots. In the last month or so, I've had an explosion in the population of snails. They're very small and most of them look like the turbo snail I have though there are some other types in there also. Most of these are tiny, but there are at this point probably 75-100 of these very small snails (turbo-like and not). This issue is probably unrelated to the pox-like symptoms on the zoas but may be related to the white spots on the coraline algae?
What do you think?
