Do LED aquarium lights cause algae?

In freshwater planted aquariums, the use of a LED lighting system for aquatic plants will promote the healthy growth of plants, which will restrict the growth of algae.

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.
Are LED lights OK for fish tanks?
