How can I properly determine the amount of watts per gallon of lighting I need for my aquarium?
How many watts you
need depends on the type of plants and the volume of the tank. Here is an excerpt from an article that will
help you determine proper wattage.
the species of plants you have in your tank or that you plan to put in your
tank and how much light that species needs. Each species of plant will have an
optimal lighting requirements, from low light to bright light. To determine the
plant species, compare photos on the Aquarium Plants Photos and Profiles page
of the Aqua Hobby website, or take samples of the aquatic plants to your local
aquarium store for identification.
down how much lighting each of the plant species in your tank needs. Give each
plant a rating of low, medium or bright. The books "The Complete
Fishkeeper" and "Freshwater Aquariums for Dummies," as well as
your local fish store, are good sources of information for this.
list and determine what type of plant dominates your tank. For example, if you
have mostly plants that need bright light, then use a bright-light formula. If
you have an equal mix of plant lighting needs, then use a medium-light formula.
a range of watts of lighting you need for your tank with one of the following
formulas, depending on the amount of light you determined you needed for your
plants. For low light, multiply one and two by the number of gallons. For
medium light, multiply two and three by the number of gallons. For bright
light, calculate three and five by the number of gallons. For example, for a
20-gallon tank with plants that need medium light, you would get a range of 40
to 60 watts (2 x 20 = 40 and 3 x 20 = 60).
