The length of time to keep your lights will depend on the type of aquarium you have running. For a freshwater tank with just fish there really is no set time. Anywhere from 1-12 hours per day will be fine. If the tank is in an area where it gets lots of indirect sunlight or simply is a bright room you can keep the lights on for less time. If it is a very dark room you can keep the lights on longer. This will also hold true for a fish only saltwater tank.
