    These pigments are chlorophyll’s (green to our eyes) and carotenoid peridinin ( which are yellow) they have so much of these pigments in thier make up that they blend the color and look golden brown to our eyes.
    YOu can translate this to a coral that is fertilised (lives in nutrient laidened water) are almost always brown. The reason is that the zoox population has increased so much that it covers the other pigments in the coral.

    The more nutrients, nitrates and phosphates, the more drab the color in SPS, eh?

    Corals may also expel their Zooxanthellae as an adaptive way of swapping one species or strain of zoo for another one to help it adapt and survive long term. But as Mojoreef nicely stated, expelling zooanthellae is a last ditch effort at life, and since corals needing light for food(symbiotic)to survive, through this zooanthellae, have been expelled the coral is not receiving the beneficial nutrients to live.
    I have a nice Galaxy coral which had been doing well then all of the sudden it went down hill fast(100%bleached for a couple days). I couldn't find the problem because all my water tests came back fine. Then I decided to change my lights which hadn't been changed for 9months(power compacts). After a few days with the new bulbs, it made a full recovery and the bright green color came back and it is growing fast. Having said that, a bleached does not mean a dead coral. There is time to fix the problem and revive your coral but time is critical.

    ATP=Adenosine TriPhosphate

    very small matter in the large matter of you helping others. :)

    maybe your spelling error was a Freudian Slip? ATP is almost like adrenaline in that it supplies power to the cells' mitochondria. (that's if I remember my cell biology) It might be what the mitochondria produce, but I think it's what the mitochondria utilize in power production.
