re: tank lights. In the morning open the curtains or turn the room lights on. Wait 30 minutes or more before turning the tank lights on.
At night turn the room lights on, then turn the tank lights off. Wait 30 minutes or more and then turn the room light off.

You could sit closer to the tank but check the water quality first
