Have this rather nice looking red stuff scattered on all the rocks, don't think it's n cyno but not sure what it is. Pic not the best as blue light doesn't make pic easy.

Hard to say. How easily does it wipe off? Is it fuzzy or rough or smooth? Can you change the settings on your camera to get a better picture or change the light settings?
 
If you can't blow it off then I think it might be just red coralline algae. Have a lot in my tank and looks pretty similar
