No I mean I set the total brightness setting to go no higher than 35% the height of the light from the water is based on the mount I have it's a ecotech marine RMS mount that is a accessory the the light itself if I'm not mistaken it's about 10-15 inches
I agree with glweek. It could also be other parameters that are affecting your corals as well. Try bringing those down and see how your corals respond.
