A few years ago I started keeping my front window blinds and curtains open over the winter day times to keep the room warm and often forgot to close them after dark. I hadn't really paid it any thought until my neighbors began asking me why I wasn't keeping my blinds open any longer because they enjoyed watching my fish tank as they drove past LOL! The blue light from my 180g tank shines to the other side of the street. The tank is a peninsula 12' from the window.
