RS has pre programs Is there one for 20k which should be 100% blue and 50% white. Sunrise at 8am sunset at 7pm. I’d choose that and monitor. That’s the program I have been running for 7 years and I have a mixed reef. You can lower if you notice coral is bleaching.Like this?


my LFS doesn’t have store hours that work with my work schedule so I’m going to have to relay on online suppliers unfortunately
