Curious, does photosynthesis equate to growth in algae? If so, would you expect oxygen to be produced by algae when the lights are on? Because in my tank which contains all sorts of algaes, turning on only Actinics light in a dark unsaturated low oxygen tank produced 0% additional oxygen (when measured by my dissolved oxygen meter). To me, that means photosynthesis is not occuring anywhere in my tank when only the Actinics are on and thus the Actinics can't cause algae to grow significantly (at least not with 96W of it).
