I think that's is exactly what is happening. Even tho they are wide angle lights, there's a hot spot under them. I wish BRS did a spotlight on the A160WE, but they completely left it out when doing the light tests. I'll see about trying to reposition the corals. The duncans I think I can save, the galaxea looks like dog poop tho.
Just move it to less light but decent flow, don't right it off yet!
If it drops any more heads I would give it an Iodine dip.
