when you say the coral turned green, is it algae covered green or the skin of the coral is green? if the coral itself has turned green i wouldnt say its a bad thing. in my personal experience, i havent had corals turn green from excessive nutrients. typically they turned brown. if you bought the coral white with purple tips, more than likely it was stressed right out and bleaching. for the most part ive yet to see a store maintain an sps piece with a white base color. i mean ive seen people have corals with white and purple tips, i had one myself. but like others have said the water quality needs to be pristine, which stores dont have. i'm not at all blaming the store you got if from just saying that the color you bought it as may be deceiving of its real color. so for now i wouldnt stress out too much about your tank quality. as far as parasites go, again the coral will usually exhibit less polyp extension and again browning out and more sliming the usual. just my two bits
