I'm sure the dead horse has been beat, I've searched around and I've asked around so I'll ask here now. Where do you have your acans for great coloration? Mine have always grown very well, new heads are always popping up like weeds. I don't get the big fluffy umbrella look like I see some acans do and my coloration always ends up drab, so I have about 6 frags that are almost the same color now. I've heard lower light for acan color, I've heard higher lights browns then out do to the excess growth of zooxanthellea but I just can not seem to find a happy medium. Where is your acan to get that insane rainbow color?
