The conclusion was as everyone is saying....The aging bulbs shift in spectrum out of the blue spectrum and more into the red. Hence making the lighting conditions ideal for nusiance algae growth.
I posted this similar question on another site and the discussion had some great input. The following was one point:

25 Elkhorn Montiporas - $15 each
