I seem to have a growth of what looks like brown/green cyano growing on most of my monti caps and one monti digi. I stepped up the flow so they are setting in direct current but nothing looks better. I don't see any of this stuff on the rocks around the corals just on the living tissue. Could this be some type of bacterial infection or something?
They will also do this if there is a sweeper tentacle or something irritating it close by.

I would suggest the Seachem Reef Dip too. Iodine dips can be irritating to most corals and you could get some bleaching. If you can figure out why the cap is receding that would be the first step.
You might want to be sure the flow hitting them isnt direct laminar flow, I've noticed that they'll get a brown algae looking stuff on them when a powerhead is pointed right at one or if they're only getting flow from one direction. They need lots of turbulent water flow, but cant stand water blowing directly at them. Just a thought.
