You need to keep your calcuim above 420 ppm. It takes time to.

The amount of light should be fine for coraline. You may need to dose a 2 part ALK-CA solution to help speed it up. Also take a stiff brush and brush the coraline you do have. This will release some of it and also encourage "stress induced" reproduction.
