PLUHH
I did search for this answer but was taking too long. I have 2 nova extreme T5 HO fixtures, whats the best amount of hrs per day to leave the 10k lights on, and same with the blues? Thanks
No I wouldn't leave the actinics on all day. The cycle I started with was Actinics on at 10am, Actinics and Daylight on at 11am, Daylights off at 9pm, Actinics off at 10pm. That gives you 12 total hours of light with only 10 hours of both in the middle. This would also give your aquarium 12 hours of no light unless you had one on a sump. If 12 hours seems to be too much and you have too much algae growth then you can take the actinics back to 11 hours and daylight down to 9 with the same type of schedule.
I tend to have mine come on later in the day that way their on when I'm home. Since I work during the day I don't want the tank on all day while I'm gone so thats why I do 10 - 10. Try to pick a time when you'll be able to enjoy the tank.
Just actinic - actinic/daylight - just actinic - off - repeat
