Our results show that algae grows the best under white light and more in blue light than red light. Therefore, our hypothesis is partially supported because the growth rate was higher under the blue light in comparison to the red group; however, the algae under the control condition experienced the most growth.

What color light is best for algae growth?
Our results show that algae grows the best under white light and more in blue light than red light. Therefore, our hypothesis is partially supported because the growth rate was higher under the blue light in comparison to the red group; however, the algae under the control condition experienced the most growth.
What wavelength of light does algae need?
between 600-700nm
Light with wavelengths between 600-700nm is the most efficient for photosynthesis.
Do LED lights promote algae growth?
Contrary to what you may have been told, LED lights do not cause algae growth any more than other aquarium lighting options. Some LED lights also have adjustable light options to dim or brighten the light according to your fish’s needs.
What light does algae grow in?
Studies have shown that green algae grow better in blue and red light because they contain chlorophyll a and b which are major light harvesting pigments and sensitive to these wavelengths.
Will algae grow under red light?
Algae uses red light to conduct photosynthesis. This scientific fact can be used to limit algae growth. Using only a little red light will slow algae growth. The less you use, the slower algae can grow.
What type of light can algae absorb?
The light reactions of many algae differ from those of land plants because some of them use different pigments to harvest light. Chlorophylls absorb primarily blue and red light, whereas carotenoids absorb primarily blue and green light, and phycobiliproteins absorb primarily blue or red light.
Does algae grow in red light?
Does blue light help algae grow?
Blue light will encourage plant growth. All kinds of plants, including algae. This is where you balance light intensity, carbon availability, and ferts to keep algae away. Moonlights for a few hours shouldn’t be a problem.
Does UV light grow algae?
So how does ultraviolet light fight planktonic algae? When the algae cells are exposed to the bulb’s ultraviolet rays, radiation destroys the plants’ cellular walls. As a result, the tiny particles of dead algae clump together, and those clumps are then removed by your mechanical filtration system.
Does blue light stop algae growth?
Algae’s photosynthesis is driven by red-yellow spectrum while it can grow with blue its growth is severely reduced. Corals have evolved to use blue and uv light to grow due to the depths that they grow.
Does algae grow in green light?
White LEDs (see the spectrum in Figure-4) emit energy in an number of wavelengths, many of them are useful for photosynthesis. However, much of the green light is not useful for algae.
