I battled it for over a month, then I chemicleaned it and now it's gone, I'm back to my regular routine(that worked for years) and no sign of cyano, tank is happy and I'm happy.
So to say that Marcos problem is because he doesn't do routine water changes is a farce, and to say that doing routine wc will clear it up in a few weeks is a greater farce.

Ok Im wrong nuke it with the chemiclean!

You did 4 20 % water changes after you did the chemiclean to get your skimmer back in order Cal. Willing to bet that helped whatever parameter was out when you had it. Maybe prevented it from coming back? No?
