The orbit ics are better for coral in my opinion, and you can 100% keep coral with them fine, personally I never ran the schedule because you couldn't alter the colors while it was live so I would set it and leave it on as you do and turn on schedule if I know I'll be away. As with what everyone else said they do get a lot of whites and would probably be better for fish only; but I was able to grow: zoas, palys, acros (high up), Favias, acans, frogspawn, leathers, goneopora, candycane and probably a handful more things I'm forgetting. Now for the spectrum I would suggest turning whites down to 30 to 45, any lower and the tank will look like it's at dusk imo, and just keep everything else 100, the corals will pop more with less whites, you could also put greens and reds down to 75 if you wish, for night I typically put it in night mode then put blues down to 1 or 2 with nothing else on. Hopes this helps, I upgraded to Ai primes to keep more corals, but I'm still using my orbit ICs over a 10 gallon reef no problems. I'll also add, your corals wont have the greatest colors with Orbit Ic lights but theyll still look great and be enjoyable to you, which is obviously what's important. I think your 'coral crash' maybe caused by something other than lights, if youd be interested in talking about your parameters, filtration and tank size I'd be able to help further assess. Also curious how long have you had the tank setup?
