If I didn't make it clear I'm sorry but here is what it say's: Ammonia is oxydized (neutralized) by Nitrites whose numbers can get off the scale. Over time of the cycle Nitrates will oxydize (neutralize) the Nitrites, and even bring their numbers down over time. And we do control the Nitrate bacteria (not as harmful as the other two) with PWC that a schedule handles most of the time, but still occational chks should be made for the increased nitrates as that count most often goes up first if ammonia is on the increase.
AndyN parameters are not out of spec for this part of the cycle as it would be expected for the Nitrates to stall since their count strength is not up to power to oxydize the nitrites. And it is the nitrites that will now grow to a big count, and nitrates will very soon start to rise in response. Hope this is made more understandable. PP
Not sure where you are getting this info. Nitrite and nitrate are not bacteria and one does not neutralize the other. Here's what happens...
-Fish produce waste.
-Waste, and other detritus, break down into ammonia.
-Ammonia is converted, by bacteria, into nitrite.
-Nitrite is converted, by another bacteria, into nitrate.
-Nitrate is then exported by whatever means, or a combination of, that you choose.
