I may have missed it, but even with sublethal effects, most of which are unknown from the provided info, the concentrations are still shown to be much higher on all studies that actually list known concentrations. Again, I don't want people to go out and use this type of ammonia, but if they do it accidentally, it shouldn't be an issue when standard steps are taken to reduce it. I just can't see enough evidence to the contrary of this--certainly not enough to take any more drastic measures than a very large water change. I know some people that would go as far as ditching the entire tank afterward, none of which is necessary. That's all I'm trying to say.
Beyond that (in reference to the articles), I see some effects of solubilization of cell membranes (which at certain concentrations is to be expected, since as far as lipids are concerned, that's what surfactants do), but not what you have written there, unless it is in a study outside of what was listed. As far as oceanic studies go, I see a large gap in that information, in that much of it hasn't be assessed to any large extent or at least satisfactorily. I also didn't see oceanic studies, but rather studies on marine fish in controlled settings--at least in the studies you listed. I didn't do any extensive searches, beyond a very cursory glance at my query earlier and a few minutes reading the abstracts (and a small excerpt from the book in one of your sources), so there may very well be extra information that may prove that levels even lower than sub ppb may be an issue. I just didn't see it from any of these sources or the ones I dug up earlier, but I may very well have overlooked it.
That being said, I still like to be cautious, which is why I recommended a good water change anyway. Carbon would be a good choice, as well, for added removal most surfactants. Basically, I am agreeing with you, but I'm unsure of what you are trying to prove beyond what was already said :huh:
