Curious as to a couple things - first of all, did you mean 1:30am in that second time phase? Secondly, what is happening between 1:30am and 2:00pm? And third, can the bulbs be turned on and off in groups of two or not?
If they can, I'd consider adding a dawn/evening photoperiod by running only a single pair of lights for a 1 or 2 hour block both before and after the "full sun" photoperiod of all four lights.
And finally, just curious, why just the 10,000K and actinic bulb choices? There are sooooo many other color ranges and options that are out there than can dramatically change the look and coloring of your tank and its inhabitants.
