Hello all. I recently acquired a nice sized efflo colony from a local reefer. The colony seems to be in good shape and the polyps are opened after acclimating and dipping. I got it cheap because its mostly brown, but there is hint of purple at the edges. What's a good place to get the coral to color up? Right now it's 24 inches away from a 6 bulb ati fixture in moderate to strong flow.

Thanks
