New tank algae ID.

[cjtabares]

I set this tank up 6 weeks ago, added light this past Tuesday 3/5, set then for a full 12(maybe a mistake now that I think about it). Starting to get some drown spots on the rocks and coral plug. Is this just inevitable with a new tank, should I do anything? Also can it be IDed with this pic? Any help would be appreciated.
My parameters are:
Po4: .08 ppm
No3: 16.6

It will always happen. It's nofthing to worry about. The tank will get covered in that, then it will start to turn green.

Ok thanks. This is kind of what I figured.

It happens to me when I introduce new rock.

That is some cool looking rock.

Yeah, I got it years ago, probably 10, when this tank was 1st setup. I have one big piece I love, but was too big for this tank.
