If you have corals you'll want to run all the lights together at least 8-9 hours a day. A 10-12 hour photoperiod is about the average for reefs, and is what I prefer. As far as timing goes, I'd run all the lamps together for 10 hours, w/ an hour of just actinics before and after the daylight lamps come on/go off for a dawn/dusk effect. HTH
PS- If your having algae issues, reducing the photoperiod will help control it. In the mean time you need to manually remove as mush as possible and find the fuel source of the algae. Most commonly it's high levels of PO4
from overfeeding, using tap water w/ high nutrient levels, etc. Having insufficient flow will also lead to algae issues. How many GPH
flow do you have total? What size tank? What type of filtration (if LR
how much)? Do you test for PO4
? What are your other water parameters- ie PH, SG
, ammo., nitrite, nitrate, Alk
? How old is the tank?
