Birdsnest help; bleaching

[Justin]

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.

What reflectors were you running before? The lumen max elites that you run now are very good at what they do. They really punch the light out. Did you switch bulbs? And then of course the obvious that you know already your params by it self are enough to start the stressing.

I just had an old school lumenarc before, I switched to the lumenmax elite as stated and raised it up a lot. Bulb stayed the same as did the ballast.

Elite pack way more punch then an lumenarc

This is a silly question but you are running the uv glass on your new reflectors right? Im sure that you are but i figure that i ask.

Yeah, hence why I raised it. The thing is, it was raised on my old tank and things were doing okay (only my sour apple BN was bleaching) and then when I transferred everything, more started bleaching.

And yes, I am running the glass on my reflector.

I've pocci bleach from adding carbon and clearing up my dirty a$$ water. It was an established tank, just neglected. Only variable was additional light from water clarity. Lost half the colony.
