CAL. 490
ALK. 9 DKH
MAG. 800
PH. 8.4
Phosphate - 0

im using 250 w bulbs with a giesemann infininti light fixture .. its stock bulbs (12K) with 4 80w actinics . running a carbon and phosphate reactor .. 2 vortech mp40 powerheads .. its a 125 gal tank

if your Magnesium is only 800, that is more likely the issue... I would say 1200 as a MINIMUM... you also have to increase the level slowly, or the rapid change can cause issues as well...

you might want to check against another test kit for your results. Sounds pretty fishy

Along with the MG, did you start with the coral at the bottom of the tank so it can adjust to the light? It could be in shock from the light as well as the low MG levels.

no .. i started it mid range now its about 5-6 inches from the top ..

White how? Bleached white or white as in necrosis? Where is it? How colorful were they in the store?
Any other sps? How are they doing?

You should start all your corals out on the bottom to acclimate them to your lights.

*Edit- And maybe the chemists can speak up but it is my understanding that Mag is normally approx. 3 times the Cal, so in your case you may have a bad kit or aren't using it properly. Just a thought. And I just noticed you are dosing Mag to get that number up... I would confirm your kit first.
