Have 2 250w 14k and 2 54w t5 actinics, over a 75g, wat do you think is a good photoperiod to setup ??? Have sps and lps.

6-8 hours on the halides I would say. You can start the actinics an hour before and shut them off an hour after your halides as well for a morning/evening effect if you like as well.

I run my halides for 6 hours. I would run your T5's an hour before and after as well. Pretty much what lord just said.

14K Phoenix bulbs are great IMO. I run my halides for 7 hours on one tank and 8 on the other
