T5 Photo Period

[Horace]

I am running 6x54w normally driven T5s on my 20" deep 75g tank. All of my SPS are in the top half of my tank so I think I should be getting more than enough light. I am just curious how long you guys are running your daylight bulbs? I run mine about 10hrs and run my Actinics about 12 hours. Is this too long?? My bulb config is as follows:

Front-

Blue+
AquaBlue+
Blue+
GE 6500k
Blue+
Aquablue

I have a 4x54w over my 55g office tank. Granted it's mostly zoos in there. 8 hrs.
