Birdsnest acting strange

[xxvietxjustinxx]

All three of my birdnest are bleaching and have little to no polyp extension. My pocillopora is also bleaching but still has polyp extension as well.

I recently upgraded my tank, transferring all my live stock in one day from a 40 gallon to a 75 gallon tank. During this time, lots of my SPS have been browning out but only the birdsnest and the pocillopora have been bleaching.

My nutrients have been all out of whack since I moved everything with phosphates being high with little to no nitrate as I have a very small bioload and a very oversized skimmer. My other parameters have been relatively stable.
I just checked the parameters today with salifert test kit and this is how it stands:

Alk 7.8
CA 420
Mg 1350
Nitrate .05 to 1
PO4 .06 (was just .104 yesterday, gfo was clogged) Tested with Hanna ULR

I also upgraded my lighting fixture but raised my canopy MUCH higher than it was before I replaced it. I feel like it could be a combination of the move and the lighting that is causing this but my pocci is literally at the bottom of the tank and it's bleaching. This concerns me. Any thoughts would be appreciated.

Did you transfer a sandbed? Add rock?

With your lights what was before and after light fixture?

too much change all at once perhaps., put old light,that there use to, back on. for a start.see if there is a change.

I did not re-use the sand bed. I added maybe one piece of rock that I dipped in muratic acid twice and it was only five ponuds max.

I can't change back the light, unfortunately. Only the reflector was different.. it was the same bulb and everythign else..
