What's "normal nitrates" levels ?I've found that higher than normal nitrates will also cause the coralline to bleach.
I don't know whats happening to my coraline... I was so happy when I saw it growing so fast all over the rocks... but now... it has loke white spots everywhere... its almost gone!

maybe they are but I can't stand those little buggers , I suck them out with every water-change ,
as for Coraline I think it grows faster on my glass and power heads rather than on my rocks , what little Coraline I got my urchin makes short work of it , never see those annoying stars on the rocks just on the glass
Mine covered my rock. That harlequin harlequin took care of them though!
