Were you able to get your cyanobacteria outbreak under control? I have an outbreak that I have been trying to treat by physical removal and large changes and it keeps coming back with a vengeance. May try a lights out period which had been effective for me for GHA.
My 3 day blackout didn't work, but it did brown out some SPS. They're still not back to where they were before. I used chemi-clean. It seemed to take care of it, but I'm now seeing signs of it returning. I think I need to do another treatment.
