Aquarium
Lighting can be very subjective, with recommendations varying
according to personal taste, intended livestock and
affordability. Use one lamp for every 24 square inches in the
tank. So for a tank 48 inches long, 20 inches deep and 20
inches tall, two 250 Watt aquarium lighting systems would be a
sufficient although higher wattages can be used.
