Since I've upgraded the lighting on my tank I've had algea problems. I have a 24" deep 120 gal. tank it contains a few sps, lps, soft corals, fish and LR. I know my nitrates are about 30 ppm (working on lowering them) no detectable phosphate, no nitrite or ammonia. I keep my other parameters right where there supposed to be so I'm blaming my problems on the lighting. Also my tank turns its volume about 12 times an hour. I have an outer orbit light fixture mounted to the top of my tank, the bulbs are 2- 250 mh 10,000k and 4-54 watt t-5 actinics. If anyone could recomend the appropriate light cycle it would be very helpful.

The light is your problem, as long as you work at the algae it will go away in a few weeks.
I do this.
I have my actinics go on a hour before my halides, then the halides go on. The halides stay on for 10 hours total.
Once the haildes go off, the actinics stay on for a hour after.
It doesnt matter what time of day the lights go on, as long as they are on for atleast 8 hours a day and no more than 12.
