Brown Algae

[dreamster41]

Few days ago I noticed brown spots all over my tank glass (front and sides), I saw few spots on the rocks which I have anchored the riccia.
I'm not sure what type of algae this is, lots of brown spots. I dont have a cam so couldn't take a picture.
I have a 30g tall tank, its about 3-4 months old. Lots of plants 2 filters (internal and a hanging filter), 30w cfl daylight bulb, few neon tetras and one paradise fish.
I dont have an algae eater except the paradise fish.

I cleaned few spots with a sponge during the weekly water changes.

Any idea how to get rid of these?

Diatoms, very common in a new tank. Just wipe it off.

Also agree. It should go away on it's own in 3 months or so.
