Running a ai prime light on my nano for about 6 months and I’ve noticed on my corals some bleaching. I didn’t realize I was running my lights for 15 hours a day. I turned the lights down to 11 hours now. My chalice, favia, freak hair all have spots of bleaching. I run mostly blues to 100 percent and my uv at 70 percent. All my parameters are stable. Is the bleaching from my light running to long? I need help!
