Continue to clean your glass.
With only NO lights, coraline will grow very slowly, if at all. By lightly scraping away the competing algae you will decrease the competition for light. Coraline algae that is there will usually not scrape away with only a light rubbing.
Snails will work reasonably well also to remove the undesired algae while not eating the coraline.

Do you at least have a blue actinic light in your setup. If so you can grow coralline.
You also need to have your pH, alk and Calcium in the corret levels. pH around 8.2, alk or dkh around 9, and Calcium should be between 400-450.
I really noticed my coralline start to really grow when I started dripping kalk.
