I think the problem is he has the lights too low. Running them at 20% is most likely not enough light. I believe he told me these corals came from a tank with MH
lighting so running the LEDs at 20% and expecting the corals to be happy doesn't make much sense to me.
I don't profess to be an expert but I've never experienced such issues transitioning a coral to a tank.
