Coraline on my light!

I just went to clean the plastic cover on my refugium light and I noticed that there is Coraline algae growing on it! Has anyone else had this happen? :confused2:

Is your light hanging in the water?

No, lol, but could it be because of the salt spray? There is alot of that on it as well.
