sorry for all of the questions
Thanks Falena! I already knew that but thanks anyways. Most are an equal ratio of red to blue. One on there is only white and blue (I believe). Which one would you do?This really depends on your personal preference
White light is a mix of all colours and is like a mild grow light by itself, but manufacturers don't seem to specify the prescice primary spectrum.
Green light is for you, it doesn't penetrate water and is not beneficial for aquatic plants. But it makes your tank very bright and pretty.
Red light promotes stem elongation and colour.
Blue light is most beneficial for plants, it promotes leaf growth. But too much of it also promotes lots of algae growth.
Have a look at the bulbs on the lights, you'll want one with white as primary, blue as secondary and red as tertiary. A couple of green bulbs are ok if you want your tank to look bright, but that's not necessary for your plants . I hope this helps
