I can't find the problem with my tank 70L 90% sps corals started losing tissue. What I did in a couple of weeks is put Fluconazole into my tank to get rid of Bryopsis. I just suspect because of that. I did water change about 10% after it killed and do it regularly once a week. What I suspect is because of toxin of Fluconazole. Many sps in my tank seems dropped and lost tissue. I just put carbon in my tank 2 days ago and it seems my sps stop losing tissue. I about to change most of water at least 60% what would impact if I do so. BTW my tank running full Zeovit system and Radion xr15 g5pro for 4 months old. Water parameter is stable with ca rx. Is anyone experienced or any suggestion would be so appreciated.
