I agree with Pog on the light intensity dont think theres a great amount of light for many corals. Are there three seperate plugs for the lights? I run my atinics for 12 hours and my daylights for 10 hours. The atinics pop on about 9:00am and at 10:00the daylights come on and vice versa for the nightatinics go off one hour after the daylights. Then the moon lights kick on for the rest of the night till morning. Heres a link to the timer I use it will run all tree plugs.
