brown algae is actually diatoms. its a bacteria that can photosynthesize.

likely due to lower light levels, or not enough plant growth at this point

as the tank matures diatoms usually go away on their own.. this is usually due to other bacterium growing in the tank doing their job to break things down and keep it clean
