So I currently have an ai prime light and am using the David saxby schedule. But I notice that every night around a certain time from 8-9 my pulsing Xenia’s close? They only stay closed for about an hour but I find it odd that they do. So my question is if you guys think that I should keep my light schedule the same or if I should change it? And if you guys know any light schedules that you find better for coral growth and colour. All suggestions are very much appreciated!
