Do aquarium plants require special lighting?

Aquarium plants have different lighting needs due to the nature of their natural habitats. Low-light plants (like Anubias) will flourish under fundamental LED setups. Medium-light plants require something nearing the stronger end of the spectrum to fill the water column properly, and high-light carpeting plants demand even more specialty systems. Use a pairing of the correct light for the plant, and potential algae issues should be mitigated.

Low Light Plants: These plants survive on very little in the way of sustenance. You can keep them under 1.5 watts per gallon, and all they do is grow slowly. Place these plants in the shaded areas of your tank, and enjoy. These hardy folks include Java Fern and Anubias. Beginners with basic LED fixtures or no lights at all, just natural room light will be happy.

Get some LED lights, preferably full spectrum (similar to sunlight). There are also adjustable versions for different plant zones, position about 6 to 12 inches above the water surface. Replace bulbs approximately once a year to maintain optimal intensity. Set a timer for the daily photoperiod.

Prevent algae by managing light and nutrient inputs. For the first few weeks in the tank, try running the lights for just 6 hours. Gradually ramp up as plants take root. Test nitrates weekly. Floating plants reduce the intensity of light reaching plants below, and tried-and-tested photoperiods work to stimulate healthy growth.

Closely note the plant's response. Pale leaves suggest light deficiency. Algae blooms indicate too long. The required adjustment is based on growth response. Healthy plants exhibit saturation of color and habitual growth. Your observation optimizes conditions.
