How long should I keep my aquarium lights on?
To provide animals and plants the lighting they need, 10 to 12 hours a day is sufficient. Installing a timer or purchasing a unit with integrated timing can make lighting easier––just set it and forget it. Keep in mind algae loves light as well. So if you notice algae growth starting, cut back on the duration. Another option is to leave the lights off while at work and have them on when at home.
Do I need a glass canopy?
If your lighting is exposed, meaning it doesn’t have a protective cover over the bulb or LED, a glass canopy is recommended to extend the life of the unit by preventing moisture from affecting it.
