t5 actinics on for 2 hours then off right after MHs turn for 6-8 hours and then have the t5 actincs go back on for another 2 hours right before the MHs go off

your Actinics are simulating a sunrise /sunset type of light with deep blue color so your corals pop. MH simulate the full sun for you tank making everything grow. So actinics turn on at 10am, Mh turn on at 11:45 or so, then Actinics off at 9:30pm,MH off at 7:15

if your ballasts are seperate put seperate timers on each starting on at a time with 8min intervals to create more of a natrual setting
