Blue Light Only?

Will turning a Kessil to 0% (only blue) kill off green hair algae (I think) or is the blue still within its spectrum?

I'm not sure .. but I know raising your mag slowly too 1600- 1700 ppm will kill it off .. not sure if that helps any ..!

I wouldnt think that running only blues will kill it. Ive taken care of a friends system where he only ran blues (dont ask lol) and he had plethora of algae
