i have a 65 gal reef with acans, hammer, mushrooms an orange chalice and some palys and zoas. i have gotten 2 acros one in march and 1 this saturday both lost color very quickly and turned white. they had full polp extension but no color. i gave the first away but would like to try with the second. i placed it in my frag tank with pcs for now. the reef has 4 bulb t5s any suggestions
