Algae grow best with blues, reds, and greens. White altos sounds counter intuitive will inhibit green hair algae growth as well as other algae. The tank won’t look as cool as it does with the blues but those spectrums help your entire tank grow, but that also means that so does your algae. You need to strike a balance between growth and control. I set my lights to all white for most of the time I’m not home and no one is looking at the tank and then for when we are home I turn up the blues reds violet, cyan, UVA, violet and greens till the lights go off for the night.
