I just purchased one and only have a few corals and am now into week 3. The first 2 weeks, my initial settings that for me anyway were to blue/purple and had a long dawn and dusk interval. The zoas opened up and mushroom spread quite well, so I guess the settings were fine
….and trolling the forums I found some info that made sense to me. Around the equator the dawn/dusk interval is very short and there is 12 hours or so of full sunlight.

So, I'm now using this cycle
TP 1 0700 A = 00% B = 00%
TP 2 0800 A = 30% B = 30%
TP 3 0900 A = 45% B =45%
TP 4 2100 A = 45% B = 45%
TP 5 2200A = 30% B = 30%
TP 6 2300 A = 00% B = 00%
So far so good but I need to give it more time. I will increase the light intensity but not for awhile. I have a 65 gallon which is 24" high.
