I've switched to Sodium Persulfate rather than FeCl for much the same reason - much cleaner and less toxic.
However, I have a Mega Electronics bubble tank and when I asked their technical support about its safety in a tank designed for FeCl, they said that the aeration would shorten the life of the etchant solution... I'm NOT a chemist, so what's your verdict on that statement?
