Frequently Asked Questions (FAQs)
1. Is full spectrum light good for aquarium plants?
Simply speaking, you can choose a light with just about any color spectrum as long as it's not too blue (such as those used for raising saltwater corals). Plants can grow under a wide spectrum of lights, so pick a color temperature that you feel makes your plants and fish look the best.
2. What light spectrum do aquarium plants need?
That being said, we can conclude that the light spectrum that supports the growth of freshwater aquarium plants best should include: At least 50% red light in the wavelength range of 630 to 700 nanometers. At least 35% green light in the wavelength range of 500 to 580 nanometers.
3. What color light is best for aquarium fish?
Blue diodes and fixtures that blend blue and white lights are ideal for reef tanks and enhancing the colors in your corals. Actinic lights emit a deep blue color in the 420nm spectrum and create the appearance of the moonlight shining through the water.
4. What color light is best for aquarium at night?
Blue LED lighting creates a calming ambiance in your aquarium. Many fish enthusiasts say the blue light serves best as a transition light between light and darkness. So, you can use the light in the evenings to help your less curious fish to come out of the hiding spots as blue light mimics the moonlight.
