Try changing your lighting sequence. I'm not familiar with the settings on a Maxspec but you should be able to modify the color combinations on ramp up and down.
I run a long light cycle too with 4 T5s. 2 actinic, 1 pink and 1 daylight. The atinics come on around 5:30 am & I turn the other 2 on at around 7:30 am. I normally turn off the pink and daylight at around 6 pm and let the timer shut off the atinics at around 8:30 pm. I also have a sump with a compact fluorescent that runs 24/7 and caulerpa.
What are your parameters like? What types of coral do you have?
