I'm starting to get a brown coating on my gravel and on my artificial plants in my 35 gal FW tank. Could this be algae? I'm not familiar with the different types of algae, and mostly think of it as being green. It's not bad at this point, and i just want to get a handle on it before it get out of control.
I don't have any algae eaters or snails, but am considering some oto's.
