Green is just one of the many colors of coralline. It doesn't turn green, it is green. Most of us are used to seeing the purple & pink, but there is also green, yellow, orange, blue, red.......
Looks to me like it's the color of the rock underneath... Maybe something is eating the coralline? My sea urchin has made 75% of the coralline on my rocks go bye bye 8-(
I also have green and purple coralline , looks cool I think . Eventually the purple takes over the Rock in my case , I only see the green in the start .
