nothing to do with actinic, while they will cause growth in algae as SAM noted it is a very slow growth as a rapid growth will raise O2 levels. your MH would contribute more in 2 hours than actinic would in 14.
you have a good skimmer and it sounds like it is working so the only thing left is that big nutrient sink we call a sand bed, HA, then Cyno, ect.. sounds like the problems I had due to my sand bed, and a familiar story among people who have removed there bed because of algae issues. my theory is that they trap nutrients, and the algae gains a foot hold by utilizing the nutrients in the sand bed, then as the algae spreads it itself traps junk and causes more available nutrients and so on and so on.
