Remove & bleach dry in the sun for a couple of days then return.
Just one rock?
If you siphon that out, does it just come back.
Good flow there?
Whenever I had just one spot, just sucked it up and increase the flow to that spot.
Not a big rock, I might just toss that one.
Chemically it works, but some collateral damage possible.
For me, 1/3 coralline on glass disappeared, two weeks after use.
Tank looks great, do the least possible.

For an isolated patch like that, I'd pull the rock out and thoroughly scrub it down with a steel brush and high-pressure spray. Then put it back in.
TUrn off tank lights for 3 days (and draw room curtains if you can) then 1 day of twilight if you have corals---then full lighting. Be sure your skimmer is operating well, because it will take up the dieoff: essential. If you do not have a skimmer, do a 20% water change. Tod this again in a month. And yet again in another month if you get a recurrence. This treatment is gauged to resemble the passing of a big wide storm on the reef, and is a natural method that will not harm your corals.

Get the lights back on, now, and be prepared to do a 3-day once a month untii you get rid of it. Cyano feeds on light, carbon (everything living has it, and so do some things that aren't), and water. There's only one of the 3 we can deprive it of that will stop it, and fortunately, light has a switch.
