IME, stability of alk, mag & cal is something to aim for but it is not important for coralline algae growth. As long as they are at least at minimum levels coralline will grow, unless PO4 is too high. This will inhibit calcification.
I didn't have a doser, alk & cal constantly up & down, yet I had coralline growing all over the place.
