So my purple death colony has lost some of its deep purple color and now at the peak of my whites it looks somewhat brownish. I tried moving it up and down my tank(still in the loser section) a couple of times but haven't noticed big diffrence. I kept them for at least three weeks in their new locations to see the effect over some time. Not much. If anyone has seen this before and succesfully dealt with this please let me know. Should they be placed up high? Does the flow make a lot of difference with them? All of my other zoas are looking bright except these ones. Should i give PurpleUp a shot????(kidding)
