This is mine on 8/16 that I got from @A Reef Creation , seems to be doing great with visible growth and a little bit of pink. (I had to black out the background because I used a close-up filter and it was right in front of my green slimer, so everything was washed out.)
I took this picture of a home wrecker and Walt Disney colony next to a Superman? Acro colony while visiting a friend. He was taking his systems down to prepare for a new tank and had them sitting in a stock tank so no lights beside what came in through the window.
