This isn't a new problem. I've always had issues with cyano and I feel like I have tried many different ways to get rid of it but with no luck. I've lowered light intensity, done a lights out for 48 hrs, more frequent water changes, better skimmer, chemipure, feed less, and got a bigger clean up crew (not an unnecessary amount though). I'll leave some pictures so you can see the situation in dealing with. What next step would you take in dealing with this? I would love to get rid of it because I can tell it affects the growth of the coral also.
I guess it's also worth saying that the tank has been established for almost two years now.
