Not sure if I understand levi could you expand on this with examples. I understand that nitrates and phosphates give hair algae a food source but you are saying low light PAR output also feeds hair algae.
Thanks
Kevin
Its not the par,but the shift in spectrum.Older lights put out a more favorable spectrum to the algae.Even with more favorable light the algae still needs po4 and no3 as fuel.Its impossible to not add these to our systems,unless one doesn't feed at all.So a shift in spectrum can be enough to tip the balance in favor of the algae
