I am on day 11. I came home to zero bryopsis and zero green algae that was growing on the rocks. Still not sure exactly what was on the rocks, but it had to be some form of the green. it wasn't hairy.
Doesn't matter, I will continue till friday (day 14), and do a water change and get things back to normal.
If it doesn't ever come back, this flucon is amazing.
teach me to ever buy a frag with anything, other than coral, growing from it.
