Yeah, in my own tanks I pretty much try to have a little low light (5-10%) on before I leave for work in the morning so I can do a visual inspection. This holds for several hours, then they ramp up for a couple of hours, then ramp down the 20's for 3, then back up about the time I'll be home from work (8.5 hours later). It's technically a 12 hour photoperiod, but only half of that with much intensity. And none of this is set in stone, I've had these things for 8 months and still find myself tinkering with the settings.
Nothing good happens fast in an ecosystem.
