Try it without lights. My coral do much much better when they get complete darkness, I believe a lot of people are in the same boat. Moonlights look cool for us but our tanks inhabitants aren’t the biggest fans of it. The main problem is led moonlights are way to bright for our tanks. The only instance where I think they are awesome was the aquarium where they got acros to spawn via moonlights coordinating with actual moon phases, they also used much smaller leds, like .5 watt then blocked out additional light from that to barely get any in the display. If you could buy that set up then yes, I’d recommend moonlights.
