I just set up my 75 Gallon tank alittle over a week ago. Its got 110 pounds of lr. For the past couple days i've noticed what looks like hair growing all over the rocks. Not like peach fuzz, more like hair. Their about 1/4 inch long. Any ideas, My lfs just blows me off saying something like "its okay, all kinda things are gonna grow in there."
