Short-term dosing:
Can I just ask what that is based off? I'm not saying to use salt or don't use salt or that I need to treat but am curious on any findings or information on that you may have here.
Long term dosing (will dig up rest on cories):
Quite often I see these discussion threads and people will be using salt and there doesn't seem to be a lot of information except that it seems to be going ok (whatever that means). Very rarely I've seen people that have tried either way (it seems to me that it takes years to come to a conclusion) - some seem to stop and some continue.

Post-Procedure
“Some plant and fish species are anecdotally considered sensitive to salinity treatments, but recent evidence suggests that others (e.g. Corydoras catfish) may be able to tolerate 0.5 to 2 ppt”

Or 0.05% to 0.2% salt.
