Do you use RO water to mix up your salt water?
Basically for cyano, lots of water changes, lots of high quality carbon (not just any ol' carbon will do) changed frequently, heavy duty wet skimming and lots of current.
I notice you run an ehiem. While great filters, any canister filter traps and holds a lot of organic debris. They need to be cleaned out every few weeks, more often when having cyano problems.
