i can personnaly verify that direct sunlight for even an hour or two a day will have an impact on your algea levels. my tank sits in such a place that the transom windows (small windows above the main window) on the opposite wall let direct sunlight hit the tank for about 1-2 hours a day... i added some closed cell blinds and problem solved. im sure an interior decorator would slap me in the back of the head for putting blinds in a transom window, but it keeps the tank cleaner with the sunlight blocked...
