PS - congrats again on moderator, in case people haven't noticed!
Nitrification is the process of converting ammonia to nitrates, and requires an aerobic environment.

Denitrification is the reverse process; converting from nitrates to nitrogen gas.

That is the general gist of things. There are some bacteria that can carry out more/less steps of each pathway and/or carry the process further (i.e. all the way to nitrogen gas rather than just nitrite, etc).

Also, thank you for your kind words. I look forward to making TPT an enjoyable experience for everyone.
