I'm just going to point it out that the tank in question is new, 6 months old I believe. This cyano bloom could be natrual and you may have to do nothing more then let time pass and keep up with good husbandry practice.
I too have recently set up a tank and I had a 2.5 month daily cyano cycle. It has finally started to pass without any changes to my current practices. Just something to think of of as you're considering the variety of response you've received.
