Was wondering does anybody have issues with dry rock turning all green... should i decrease lighting..
 
tanks been up about 3 or 4 months.. should i decrease lighting or leaving lighting the way it is.. My light is an ai nano led setting 50 percent on white blue and royal blue
 
It's fine thats how mine looks. And I wouldn't brush it off. In time the coraline algea will grow in and that's all. I believe it's just bacteria on the rock.
 
That happened to me when I added a couple pieces of dry rock. They started white, then turned green, then brown, now they're nice and purple. Parameters never went out of normal ranges.

Me too, and my tanks been up for years. Must just be the normal process dry rock goes through, it's happened to me each time.
 
My dry rock turned dark green with some lime green in patches. Now its starting to turn purple. I scrape existing coraline off with pumps shut down to spread it. It's works very very quickly. Little purple spots start to take over. I do this after every waterchange. Coraline uses tons of calcium so keep up with dozing and waterchanges.
