Actinic Lighting and Hair Algae

[Jaws]

Can too much actinic lighting be attributed to hair algae growth. I'm concerned that my actinics, because I turn them on in the morning berfore I go to work at 9:00am and then don't turn them off sometimes until almost midnight, might be contributing to hair algae growth. I wouldn't think the intensity would be enough to do it though except I do have 4 96W actinics.
