Morning when you wake up? Afternoon when you come home from work/school? After dinner when the actinics are only on? Before you go to bed when you have the moonlights on?
My personal favorite is at night with the moonlights...it is so serene and peacefull watching the blue lights penetrate through the water and see the shadows of the fish as the ones who are "late nighters" swim around peacefully around the tank in near darkness and shimmer in flashes of cool blue light. Very soothing feeling to have before going off to rest and ultimately sleep. Just puts you in a good and relaxed mood.
