Does the Tek light have separate plugs for a number of the bulbs? Or is it always on or always off only?
My experience is that actinic bulbs don't really make much of a difference if they're always on, on my softie tank, I have 4-t5s and like a mix of "daylights" and "blue" (different brand names have different color names last I looked), I originally also tossed on 2 actinic (purple colored) bulbs, I think they were giesemann brand (german) and it really didn't do much. The light was already blued up, and the only think it added was a little night time viewing when the main lights were out.
