So I had a cyano outbreak, kinda watched it happen. Then my corals closed shop and i found cyano covering them. I bought some chemiclean and the next day it was almost gone. (Great stuff) I would suggest for anyone that has the same problem and uses ecotech powerheads, put the foam covers on. The cyano will start releasing and the pumps will collect it on the guards. Makes life easier to clean up.
