nitrite process, or something more “poisonous”?
>> Good moves on your part, paying attention to what is/was going on in your tank… removing the remains (siphon next time…) and placing the activated carbon… Only time will tell if much/any noxious material effects there may be from this event… There is not “much” to anemones (mostly water), so “stinging/sticky” elements are about the principal worry (perhaps causing other life to in turn cause nitrogenous problems)… I would execute a large water change (50%) out of general principles and leave it, and watch, otherwise at this point. I’m sure you can understand why I’m so guarded about new folks to the hobby getting involved with anemones. Am hopeful you will be of the same opinion.
