I'm sorry it's been a while since I set up a new tank. I've had my 240 up and running for about 2 weeks now. I looked today and I'm starting to see brown like algae on my sand and rocks. Is this normal for a new tank?

do you have pictures? typically this is called cyano bacteria or diatoms (two different things), and is definitely normal for a new tank.
