you generally want actinics on the the edges, and the whiter lamps towards the middle.
actinics should run first and cut off last, you can run them for 10-14 hours, and the whiter bulbs should represent the brightest part of the day, so they should run 6-8 hours. its really your choice for the actual start and stop times.
superactinics and pure actinics are great bulb choices, and then the rest depends on what color you really like your tank to look, more blue should be higher K and more white should be 10k ish and more growth, and more oranges and reds mixed in should have some 6500k.
