Alright I switched it. What about the schedule intensity??White leds tend to really increase par levels, and since leds are a more focused light the corals seems to take a long time to acclimate. With that said, you can acclimate any coral to any light, it just might be a much slower acclimation than what you think. When you purchase new corals for your tank try to find ones that are currently being grown under leds, it will help them acclimate easier to your tank.
As for the ones in your tank already I would just set it to AB+ and leave the acclimation as is. Give it time and see what happens. Try to just set it and forget it, changing things isn’t gonna help the process. Corals are extremely adaptable and will eventually come around.
