I'll try adjusting the programming and lowering the intensity. Sounds like it could be too bright / too close (at least I'm not running at the higher intensity settings!).

I have mine 7 inches above waterline and I find corals on the higher end of the rocks are encrusting and growing better then ones placed lower. Colors are excellent, no colors fading or dying off. With that being said, these corals are sps and I would not place LPS or softies high. I now run 100% intensity for I think 3-4 hrs and I also have a lot of flow in my tank which I think helps as well.
