Is that so?

Because when the rocks first came, there was almost zero Coralline Algae. Then as time progressed, more and more started to develop and grow. It was only until recently where the rocks began to turn white and bleach. So I think what I did was decrease some of the photo period...

So I am unsure as to what might be causing this?
