Cyano on a rock

I got good values of the water.. but from a rock where died a coral started a ciano colony.

I could temporarily take that rock out of the water.. but what do you suggest? I already tried just to wash it over but it came back

How long ago did the coral die? If it's only been a short time, I would just let the system adapt to the change.

nutrients are ok.

The coral was dying 2months ago more or less... (falled in an Euphyllia). actually didn't die, at the moment it is in another tank to cure.

I could take the rock out of the water but just washing it I guess it won't work

Washing it won't do much, most likely, but you could siphon off the cyan once a week or so, to remove nutrients. In all honest, I'd just wait, but there are chemical alternatives. Just running a bit of carbon dosing might help outcompete the cyanobacteria for nutrients. That doesn't always work.
