I have a timer for my lights. So that our family is able to enjoy the aquarium, I have it set to come on at 7am, off at 10 am, then on at 5pm, off at 9 pm. This makes it a total of 7 hours of lights on. Is this okay, or does lights-on need to be consecutive hours? The tank gets no direct sunlight, but it is in a room with windows. The windows let in just a little sun during the day, just not directly on the tank. Thanks for any help!
