This guy was having a problem with cyno in his tank. He tried various methods to rid it with limited success that is until he tried an Oxydator. I have never claimed an Ox6will cure cyno only that is an aid for its eradication. Anyway worth a look.
Worth a look to see what this guy believes. It claims it cured his cyno problem and I can well believe it.
