How much light does your aquarium require?
The quantity of light required for marine aquariums will vary depending on the life forms kept. In fish-only setups, 2 Watts per gallon is sufficient. Reef-type systems containing primarily soft corals should have a ratio of 2 to 4 Watts per gallon. A deduction of 15% to 20% of the rated tank volume is permissible to account for water displacement due to live rock formations.
How much light does my freshwater aquarium require?
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)
