The quick answer is yes, you should schedule the lighting for your fish and plants. Your finned friends and flora need a daily break from bright lights. Aquarium fish require a regulated cycle of day and night to mimic their native environments. Since most aquarium fish originate from tropical environments that receive 12 hours of daylight and 12 hours of darkness, you want to emulate that cycle with your lighting. If you don't have live plants in your tank, a period of 6 to 8 hours of light is a better choice for reducing unwanted algae growth. You can use a simple timer with your light fixtures to control the light manually. But if you have the Aqueon OptiBright Smart LED Light, you can use the Aqueon BlueIQ app to set a schedule for lights without having to manually turn them on and off. Automating your daily aquarium lighting ensures changes happen on schedule, whether you sleep in late on the weekends or are traveling away from home for a few days.
