Hi and welcome Dunken,

Yes it sounds like it could be algae of some kind and direct sunlight could well be a problem - specially long term.

I think the others would want a bit more information to help better.

How long has the tank been cyling for, any fish in there?

What are water parameters, NitrIte, NitrAte, ammonia, pH and phosphate?

What lighting period?

Brown algae is not really a problem unto itself -- it more just looks awful. It's generally caused by too much light (especially sunlight) and/or high nitrate/nitrite/phosphorous.
Treatment: Siamese flying fox. It's the only kind of algae eater that'll eat brown algae. Wipe your glass, reef, etc with a soft clean sponge -- it comes off really easily.


Cheers!

I believe otocinclus also eats brown algae. Most fish will eat it a bit.
