While I was researching lighting I came upon a scientific study that looked at the motility of algae in a coral. I had my lights at blue for 3 hours, then whites on also for 6 hours, with another 2 hours of blue only. And after reading the data, I changed to 30 minutes blue, whites on also for another 5 1/2 hours, then just blue for another hour and a half. According to the my interpretation of the research, I had my blues on too long before whites and I was missing giving them enough light as the motility was peaking.
