What is full-spectrum aquarium light?
Full Spectrum lights emit all possible wavelengths of visible light and most closely resemble natural sunlight, perfect for planted tanks. They typically contain a mix of all colors of the color spectrum.
How many hours a day should an aquarium light be on?
Planted tanks only need about 8-10 hours of light each day to grow healthy plants. Of course, the photoperiod depends on the types of plants you are growing.
Plants with a low light requirement might do well with only 6 hours of light, while more demanding plants might need more than 8.
