Hi all,
One of my Zoa frags developed a coating of white film or sponge over the past 2-3 days, and the Zoas can’t open. Right now it’s only on one patch, other Zoas are looking fine.
I tried gently scrubbing it off with a toothbrush (outside the tank) but it wouldn’t come off.
Introduced this Zoa over a week ago and was fine then until the past couple days.
Parameters:
Calcium: 457
Alk: 8.3
Mag: 1380
pH: 8.2
Phos: .02
Nitrate: 0
Salinity: 1.025
I figure I can’t save these now and will sadly be disposing of this frag, but was wondering if anyone knows (1) what it is and (2) what could have caused it?
