well, looks like I am one of the few. I treated my tank and the bryopsis went away. 2 months later it came back. But this time around, it came back and grew very fast. When i had it before, it was in a small spot and grew very slow. This time, it came back in the same spot, but is 2-3x bigger than it ever was.
The only thing I have changed since the initial dosing, was dosing my tank to raise the alkalinity. im pushing high 8's, to low 9's at the moment. other than that, nothing has changed.
not sure why it came back again, let alone it growing fast
