You're preaching to the choir, perhaps reply to the post
that made the claim. Everyone ends up inoculated with BGA,
and BGA doesn't care about NO3 - it will fix it's own nitrogen.

There are a great many types of BGA. As I understand
it they do not all fix nitrogen. Do the types found in freshwater
aquaria fix their own nitrogen? If so what types are they?

Thanks
