Coralline Algae Growth

[thewackyreefer]

I'm about to start cycling a bunch of dry rock in a trash can and am curious if coralline algae will grow if there's no light on the rock. I know it grows in spots in my tank where it's "dark" but obviously there's some light hitting it as I can see it.

Thanks all.

No it wont without light.

Well, looks like I'll have to toss the old PC over it!
