After reading through many posts I see that I am not the only one having issues after using vibrant. My green hair algae is completely gone along with my bubble algae. But now I am dealing with cyanobacteria. I have cut back on my feeding I run an upflow algae scrubber I run npx pellets, as well as an oversized skimmer, skimming wet. Just wanted to see what everyone else was doing to combat the cyanobacteria.
