Good day everyone... Well I picked up a new large blue acro colony yesterday from my LFS, it had decent polyp extension and had light yellow bases with blue tips, last night I acclimated it over one hour by drip line and placed it on my sand bed. Today it has lost most color and is white and yellow. No flesh has been lost and has nice polyp extension, the under sides of the polyps are still blue... I have over a dozen other large acros and two large clams, several large LPS corals, all are doing excellent with excellent colors and growth. Mag is 1360, Alk is 8.6 calcium is 440, nitrates 0 and phosphate 0. No other problems in the tank all seems normal. The acro is maricultured, could it be to much light? ( reef breeder photon 48 peaking at 30% white 65% blue any higher I have problems) tank is a 90 with two RW 8 wave makers, 38 gallon fuge, skimmer, carbon reactor, uv. I moved it to a shaded spot in the sand... Looked closely see two acro crabs but nothing else. Stress, lighting, bad luck? What's your thoughts? Will it recover in the shade for a few weeks? Thanks

Well not sure how long your LFS had it but I just went through something similar. I went to LFS and he was unboxing Fiji acros. I helped him out and bought all the frags that came off the colonies. Some only 1/10 an inch. Were talking tiny. Everyone over 1/4 inch besides 1 is still alive. A few stressed and went white but now a few weeks later are coloring back up. The rest are happy with great pe. I expect footing soon. Thing is they went from ocean and sunlight to box water and dark for 2 days. To his water to mine. Sps love stability and both of us just changed that 3 times. I left mine in the bright light of my ati t5. You say your experienced with acros so I am guessing it'd just stress from all the changes.
I am just kind of confused by it, I've had acros go brown a few times or no polyp extension for a few days to weeks but never turn white like this other than when I had one fall into my hammer once a few years back ( he didn't make it but that was rtn). I have fragged them on purpose and accident several times and never had any problems... Just curious as to what happened. My first thought was the LEDs then stress. Just wondering what the best course of action would be... My current plan is let it be in the shade for a few days, slowly bringing it out to the light and feed it at night when it's polyps are open for a few weeks and see how it does...here is a pic of tonight with just the lights in my office on... Has nice polyp extension... But...
