Is this normal?

[krisalexander]

Well it is just about a week into cycling my tank, and yesterday and today i have noticed a huge increase in brown algae, makes the rocks look like they have rust on them kind of, and the class is covered..anyway.. just wondering if anyone has experienced this? is it normal? how to reduce it? it is making my glass and rocks look pretty ugly..i cleaned the glasss but the rocks not so easy..

thanks
