On my 30 gallon tank I have noticed some brown algae growing on the glass and the live plants.

What is causing this? I've seen mixed reviews on how to stop it and get rid of it...

Some people say to leave the light on longer.. Some say turn it off sooner...

I know I didn't have this problem until my hood light stopped working and I was wanting on a new one to show up in the mail cause petco or petsmart didn't have my size....
