Hello,

Different types of coraline grow at different light intensities. So, eventually certain types of coraline will grow your tank. Growth rates vary with different kinds of coralline.

As far as your other corals, you can slowly adapt them to the high intensity lights that your tank has. The process takes about 1-6 months. You don't want to photo-shock the coral -- which is what will happen when a coral is quickly moved from a low light level environment to a high light level environment.
