zoas turning white

cimmorine · Jan 9, 2014

3 days ago I switched media reactors to an avast one similar to 2lf. Didnt realize it was missing a top sponge so some carbon and gfo got released into the tank. I did a water change a day later and today some of my zoas, which were doing great, have lost their colors, lost their skirts, and open like a swollen eye....
Any ideas? Its only 4 of them but I can see others that have been fragged for well over 2 weeks now starting to lose their skirts too....

Are there any other Coral in system and if so what has been their reaction ? Does not sound good and not understanding why they would react so negatively to
Carbon and GFO like that.

Cheers, Todd

In the tank I have a mini colony of hammers, not anywhere near them. Chalice, montis, digi, ricordias, a little bit of everything but only the zoas that have been fragged 1 weeks agk are being affected. .
