Try moving pices to different areas as long as you have good polyp extension then let time do its thing. Also IMO ozone is good but not a huge factor for me. Orp can and will drop and raise through out the day.

+1 one. I have had an Orp probe on my tank for 3 years and have watched to go from 300 to 450 all in a matter of a day without any noticeable changes in my tank. Some days it'll sit at the low end, sometimes it will sit at the high end. I've read up on it as well and still don't really understand what the heck ORP is telling me LOL.
