I have a 50 gal FOWLR aquarium that has been up for about one year. I have a FluvalSmart 2.0 LED light bar, but am not sure what combination of red, blue, green, & white spectrums to use. I tinkered with the settings after reading several articles and I don’t know the original factory settings, and see no way to return to them. Any suggestion of the proper balance of spectrums would be appreciated.
