So I recently upgraded my lighting from 2-250W DE Phoenix bulbs in a not so perfect but modified Odyssea fixture that were being driven by 2 lumatek dimmable ballasts on the HQI setting. To 2-250 SE Radiums in LumenMax elite fixtures runnig off the same ballasts on the HQI setting. I started out with two layers of screen to acclimate all to the new lighting but after about day three everyone was really stretching out trying to soak up the light and I removed one. Everything looked and reacted fine.
Fast forward five days later (Sunday) and I removed the remaining layer of screen and again everything acted/reacted fine. I did notice that my S. Haddoni was moving to left a little bit but that was fine since it was moving more towards the light instead of sinking back to the right away from it. Now here comes the interesting part.
Last night I got up to check and make sure the blenny made it to his hidey hole instead of the nem after the lights went out and it did. All looked normal like it would any other night after lights out so off to bed I go. I wake up this morning and peek at the tank (lights are still out. picture was taken at lunch but looked the same) and this is what I see!

Uh oh. Run a quick set of tests which are:
Salinity: 1.026
PH: 8.3
Amm: 0
No2: 0
No3: under 5ppm
Alk: 7
Ok looks good. This is typically what the nem looks like so I was a bit shocked when I saw the above.

Not doing aything drastic since I can see it back in the rocks I leave for work. I came home at lunch and the tank still looked the same as the morning that's when I took the first picture above. When I got home from work this is what I see and is still pretty much the same.

So now that the back story is out of the way on to the question. Would the DE Phoenix bulbs being run on the HQI setting put out more PAR then the Radiums and thus start the moving towards the light? The nem was introduced on the 20th of November and hasn't moved more than an inch to the left or right during this time. It just seems wierd that it would travel probably 15 inches around a rock to move 4 inches to left of it's previous position but more towards the light.
All responses are appreciated.
