FLOW!!
One thing I forgot to mention is that flow is the other part of the light-food-flow equation.
More flow and more food (or even nitrates) can help alleviate a problem with lighting.
If he's still laying flat on that plate of rock, that's almost sure to be a low-flow situation. Stick his plug into a frag rack, or a crevice so he's at least upright.
He'll be much more able to breath if he's at least roughly upright. Protruding out into a strong flow somewhere in the tank is the idea. :)
And of course, move him elsewhere in the tank tomorrow if you're findings withe the lux meter prove to be very different than the originator's. (They may or may not.)
ABOUT YOUR LIGHT
While we wait for an actual reading from your tank, I can tell you that 300 PAR is about 13,000 lux.
About what I run my dim tank at....SPS do well, but it's on the low end of their range. It's conceivable that if you took my SPS from that tank and plopped them into my (or maybe yours) 50,000 lux tank, they might bleach.
Frags are amazingly adaptable, but if there were other stressors on top of light and nutrients (and being fragged!)....like flow, overheating, acclimation stress, etc....
Corals and fish and people are all the same in at least one way....all stresses are cumulative.
Let us know how tomorrow goes - my fingers are crossed!
HOMEWORK ;)
All the stresses mentioned are ON TOP of the daily stresses of being a coral.....check out some of the attached PDF's for an idea what a coral is up against day to day. :)
