In the past, what we would use to treat Zoa Pox would be to use a fish medication called Furan-2, and it worked for the most part. However, from what I hear these days, Furan-2 isn’t really being sold or manufactured, or maybe it’s just banned outright for some odd reason. So if this isn’t something you already have in your arsenal, there’s a few other ways to combat Zoa Pox. One way is to take some stainless steel wood carving tools and individually “pop” those zits and then just rinse them away. As long as you keep those zoas clean going forward, you won’t have another issue with Zoa Pox.
Another thing you can do if you aren’t comfortable doing dips and/or don’t want to go about popping all those little zits, you could just eliminate the root cause of the pox and just blast your Zoanthids with flow to dislodge all that irritating detritus. After doing that, over time the coral will probably be fine, it’s very uncommon for Zoa Pox to actually kill an entire colony of zoas.
