I have had 10 lbs of live rock on top of 60 lbs of base rock for a little over 2 months now. The base rock has been sitting on 65 lbs of live sand for an additional month on top of that. The base rock is a cream white but recently has gotten some funny colors on it. I have seen a lot of established tanks that were purple everywhere, which I know is good coraline algae. My rock has spots of a turquoise which looks like a child has drawn on it with a turquoise crayola crown. Last week I started noticing a darker green which is in thousands of tiny specs. Now I am starting to see a tint of purple on it too. I am guessing this is the good purple algae.... but what about the other 2?
