I'm not new to the hobby, but it's been a while since I've started a new tank. About a week ago I started up a 150 gallon and the tank, even with a decent bit of live rock, is going through "the uglies" and has a good dusting of brown algae over the sand and rocks. Should I just leave it be and let it run it's course, or gently vacuum out what I can to remove it from the tank?
