Hello, I wanted to share my experience using fluconazole. I dosed my tank yesterday to fight bryopsis. Within 15 minutes of introducing the fluconazole, all of my LPS corals retracted into their skeletons. One of my tiger torches experienced polyp bailout that evening.
When I woke up this morning, one of my healthiest torches was melting. I suppose you could call it BJD, but it really wasn’t brown—it looked more like one of the polyps simply disintegrated. None of the other LPS in the tank look like they are going to die. I dipped both torches in a high concentration of Lugol’s iodine and now have them placed in my sump area.
What I think happened:
When the fluconazole entered the tank in a high-flow area, it still clumped together. I noticed some of the medication settle directly on the torches. I think the high concentration of the medication may have “burned” the coral.
I did some Google searching but haven’t found any definitive information on what the actual cause might be. I have read that other people have experienced coral die-off during this treatment.
If anyone has definitive information on why this happens, or how to better prevent it when using fluconazole, I’m sure the community would appreciate the insight.
