I read an article in Coral Magazine about these things and just how toxic even a few grams of it can be. Got to thinking about all the bubbles popping in the skimmer and sump and thought it would be worth seeing about to remove them for a while. Fortunately, I was able to re-home them in a friends tank.
Immediately, my son began sleeping through the night and hasn't had an issue since. That was nearly a month ago.
Suffice it to say, we won't try them again.
Wow...that's a new one. The evidence seems solid. Zoas come in all sorts of toxic strengths, most are pretty benign. Some are lethal as heck. Those toxins are extruded as part of the Zoas protective slime coat. It certainly isn't impossible that some of it could be aerosolized as a result of skimming action. But that's the first I have ever heard it reported.
