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
