Here are some photo updates.
I just wanted to show the progress of the coralline algae colonization of the rocks.
I see different strains duking it out all over the tank which creates a nice variety of colors.
Although the intention is to show the coralline algae, I can't avoid getting photo-bombed by the corals too :)
I turned off the blue LEDs while taking pictures so that it does not create an artificial tint to the rocks.
FTS with Blue LEDs turned back on (Whites 20% / Blues 40%)
The most obvious color strain is the bright purple and appears to be dominant at this time.
There are also several color strains which might not be visible on the pictures. There are spots of dark purple, red and green which appear to be easily overtaken by the bright purple ones.
There are also very dark maroon strains encrusting on the surface of the overflows which make them look like swiss cheese at this point.
Here's a picture of the rocks when they were brand new.
