    On most tanks about 18 to 24 in deep you probably want about 400 par at the top of the tank. This is a med light tank.

    With led with not too much blue , 6000lux is around 100 par. So 2400 lux is about 400 par. But I'd start at around 18,000 lux. See how it goes for a week or two. Then bump it anothe 50-100 par or lower it if you feel it's needed.

    Some coral are generalist , even in the same family. A digitata can be lower and higher light. So can all sps , zoas and other softies. And there are also true low light corals in each family.
    Be knowing the set par in your tank you can make coral buying choices too.
