Need help from the experts

[Trigger Man]

I would try fragging, in my case it was my torch and it started with one head getting slime and then moved to another. At that point I cut off the infected peices (as it was a branching torch) and hoped for the best. My remaining couple looked good for about a week, but then started deteriorating. Everything else in my tank including my hammers that are located a ways away were not affected. So keep a eye on your remaining ones, and maybe give them a coral dip if possible.
I hope this helps a bit, as hopefully someone with more experiece on the matter will be sble to chime in as well.
