A lot of people run them with their daylights as well as before & after........ So if your MH's are on for, say, 7 hours, then the actinics would run 8 or 9..... either a half hour or hour before & after.
Wanna calculate the cost of that new reef tank?? Take your worst nightmare, double it, and you're halfway there.
