Hi all,
I'm honestly not sure it helps us a lot.

If you are reduced to using salt (NaCl) to control nitrite (NO2-) poisoning, you really need some help long before that.

The mechanism by which Cl- ion reduces NO2- intake is literally just a numbers game, as the ratio of Cl- to NO2- ion rises the chance of a Cl- ion passing across the gill membrane rises and nitrite poisoning symptoms are "reduced".

It isn't even really a sticking plaster over an open wound, and for me would be emergency triage as a last resort.

cheers Darrel

When uncycling happens, it is the usual approach to combat NO2- effects temporarily until the nitrification catches up.

All true, and yet people confront "brown blood" problems occasionally. Triage is exactly what it is.
