I've had this lighting schedule for almost two years now and I have had very little algae problems. I scrape the glass about once a week, like most people I think, but don't have much for green algae anywhere else. I am using PC
's for the main daylight cycle, 2 65 watt daylight bulbs and two 55 watt actinics, and then I also run 2 15 watt NO
flourescents 15 hours a day. I like to have just the actinics on around bedtime and when I wake up just for the look I guess. Supposedly the actinics alone won't grow much for bad algaes, but the corraline algae thrives under low light. I also run my caulerpa fuge/sump 24/7.
