Coralline color

[Corona007]

Ok, So I got coralline growing everywhere but just the last week it has exploded on the back side but it's green. There are a few pink spots in the same are.
The plexiglass side its on is where my circulation pumps are and they are caked with the pink and no green.
I thought it might be algae but the texture and growth pattern resembles the pink. Also it won't come off with mag float but can be scrapped off.
Tank will be 1 year in April.

Coralline algae does come in a variety of colors, so what your experiencing sounds normal to me. Why it's green instead of pink I have no idea. It could have something to do with the lighting, maybe an abundance of one element in the water right now as opposed to another etc.
