Brown algae?

[FishDaAx]

Hey guys have had my 14 nano tank running for only 5 days. I was running a temporary light on the tank till today I got my LED lighting in and a small power head. Anyway I started the tank with live rock, live sand, and real ocean water(bought from petco)

This is my first saltwater so I am a noob here. Is this growth on my rocks brown algae?
