Anyone ever have their Coraline Algae turn green? Whatever this is, it's putting a dent in my purple Coraline and taking over the rocks. It's hard so I know its not slime algae or hair algae...:ermm:

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.......

Hmm my LFS told me its bad calcerous algae growing and killing the Purp coraline algae
 
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 .
 
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-(

No urchins in the tank. Just 2 clowns and some hermits.

Hmm this didn't start until I started using Purple Up additive.
 
If you're using reef salt and watching your levels, purple up is a waste. It's just concentrated ca and mg.
