The pinkish algae has not matured anymore yet, it is just stationary.
Okay, here are some more pics. I've taken some shots of my refugium, and a frontal shot showing the maturity of the rock with the hood lights on, and then with them off + flash.
A couple of days after adding my LR:
Tonight, a noticeable difference particularly considering the diatoms. Unfortunately due to the bright lights, the diatoms on the sand barely show, they are a rich brown, however:
With a flash, just to demonstrate the ripe colors:
The refugium, before adding a light.
The sponge is to break the stream, as I've read chaeto prefers low-flow zones. There's about 1.5 lbs worth of LR in the fuge, which in an 8G, can make quite a difference. Forgive the butchered texture, I was scraping at the glass with a small razorblade for hours. The waterline is nearly to the top, I've ignored the water load limit because there are no bio-balls.
I'll post some images of my light mod which I'll hopefully do in the next day or so.
