Purple coralline algae turning green? Advice please.
 

I have this beautiful purple coralline algae and over the last 2 days parts of it are turning a very pretty green.

Has anyone heard of it?

I'm currently merging the contents of my QT tank with my reef and noticed this. Is it anything I should be concerned about?

Any inkling what might cause this?

I understand that coralline can turn green and blue but I thought that was before turning purple. This is a bright green over the purple.

Anyone, please? :biggrin:

Coralline algae comes in a rainbow of colors. So the green on purple could be two different color forms of coralline algae, or possibly another type of green algae all together. A clear picture will really help out.

Ha ha ha! I take absolutely horrible pictures. :redface: I'll see what I can do.
