Anemone died?

Anemone died today, purchased Thursday. It was a Condy. Drip acclimated for 2.5 hours. Did fine the first two days was feeding it small pieces of cod (not sure if it was unsafe as I couldnt find any negative indications online) had the LFS test the water before hand just to make sure, he said everything was okay. I tested the water after I removed it and everything was good pH 8.2,NO3/NO4 0/0, salinity 1.023 (I know idea reef is 1.026 but I didn't want to raise it to fast) 75 gal bow front with 29 gal sump established for over a year and skimmer rated for 200gal. The skimmer was new and still being broken in so not sure if there was too high of phosphates (still have to mow hair algae every now and then) light is LED specs-[(13) 6K White, (14) 9K White, (17) 10K White, (3) Blue, (7) Red, (3) Blue Lunar LED`s] other corals include mushroom, zoas, and star polyps but no signs of stress in though. Any ideas ?
