I love that quote. I had a rock piece dry a few days to kill them after scraping them off and after i put it back a week later i had more growing on that same rock.
great read. one thing i thought id mention, i have a nice xenia colony growing and actually just fragged my first piece. when i got them they pulsed like crazy. my ph is 8 -8.1 and i read that they needed to be at 8.3. i adjusted upwards and they stopped pulsing. now the ph has been dropping again and they havent started to pulse like they used to.
this is my xenia pulsing after a long tank move with rocks going out of the tank and then back in.. Nitrates were high...The xenia was pulsing even more...
