I am starting to get great coralline growth on the back glass, PHs and live rock....but it's more whitish, not purple. is my lighting causing this? Is there anything I can do to make it more purple? Is there some trace element missing maybe? Tank is a 30 long with 4x39 watt T5s, 2 10000K and 2 actinic.
