The reason I ask is that your cycle may not have stalled but you may have a bit of a bacteria unbalance. If you have a large population of Nitrospira bacteria you could be converting enough ammonia directly to nitrate and because of that have an under developed population of bacteria to convert nitrite to nitrate.
That's what I was worried about (thinking of your article) and why I used 3 different bacteria in a bottle products. Ones that I heard had different types in them. Right now, it feels like it's right at the cusp of being done. Remember the nitrite was at 2ppm for a couple weeks and after using the Fritz stuff it went down to .25ppm so something got kick started.
