I had absolutely no cyano but didn't use vibrant. It completely killed all Bryopsis and GHA in 14 days. I'm leaving it in the tank a while longer as long as coral continue to look good in case of hidden roots. Most do water change after 14-21 days.Most folks myself included had a cyano outbreak, but it was due to using Vibrant prior to and during the fluconazole treatment.
