To achieve appropriate lighting, a general rule is to have a range of 1 to 3 watts of light per gallon of water in your aquarium, subtracting 10-15% of the tank volume to account for volume of materials inside the tank. Adequate lighting range = (1 to 3 watts/gallon) - (10%-15% of tank volume)

For planted aquariums, the quantity of light for faster growing plant species should approach a minimum of 3 Watts per gallon.
