The problem is that this is happening all over my tank. I had 6 clusters of zoas scattered all over, and i only have a handful of zoas left that are alive. Some of them were on a rock with a larger (predatory-type) green polyp on it, and he's doing fine.Some of them were alone, and they are also dead. It does seem to be a water issue, but I have done all tests I could find in the LFS
, and nothing seems to be wrong. pH, Ca
, temperature, salinity, iodine, all within norms. No detectable nitrates, nitrites, or ammonia. I am at a total loss.
