A bit baffled?

[JD'sReef]

So here goes!
About a week ago, my "Rose BTA" was on a rock that fell out of place. Seeing this, I immediately placed the rock into a different location which was more secure. Since this time period, the Anemone shrinks down to almost nothing once the lights turn on (that is right, on). Because of this I moved the rock it has attached itself to to another location for the third time. The BTA has no visiual flesh wounds from the movement. It is just that I find it odd that under the lights it shrinks to nothing almost looking dead. However; when the lights are out for the P.M. cycle of the tank, it fills with life and looks better then ever. Any Ideas would be greatly appreciated.
Parameters
-175watt MH bulb replaced with a 2000K on May5 of 2007 (the BTA s located about one foot "directly" below the MH. currently on from 1-9:30 pm.
-50/50k and 100k standard florescent tubes changed June 4th of 2007. Turned on from 12noon through 10pm.
- Ph is 8.1 in the AM "no lights"
- Ph is 8.3 with the lights on
- Alk is 6 to 7 DKH
-Salinity is 1.025 or .027 depending when tested.
Sorry for the long post fellow reefers, this just has me baffled. At first I thought the PH was fluctuating but now I have other thoughts.
Thanks

what was the light like before the rock it was on fell, I mean did you put it into a brighter spot?

I most def put it into a brighter spot. However; wouldn't more light be better for it? On top of that, wouldn't the BTA move if it was to bright? Maybe tomorrow I will try a less intense (light) spot.

My guess would be that the temperature is spiking too high during the day. I've seen them do this when that happens. If your thermometer reads acceptable, you may want to try another thermometer just to be sure. Aquarium thermometers are notoriously inaccurate.

Do you feed it often. I've found that when mine have become stressed like this, feeding it usually helps it to recover, as long as it will accept food.
