Algae growth?

I just started up my 60 Gal. Reef tank about a week ago. I purchased Catalina water and have been adding Calcium, Iodine, & strontium. I did a water testy yesterday and everything came out good. My PH is at about 8.3, 0 Nitrates, 0 Nitrites, Non detechtable ammonia. My alkalinity is at 2.75 and my calcium is at 450 ppm.The temp is 80. And now for my question. I am starting to get a slight build up of algea rust colored to greenish only on the rocks. the water is crystal clear and so is the acrylic. Is this just a stage of the cycle or is there something I'm not checking?
Any advice would be greatly appreciated.
Thanks
