its been dosed so much w ammonia the nitrite may not clear for a long time. todays updated cycling doesnt factor nitrite anyway, you are set.
set = if you changed out all your water (removes bac from suspension) and refilled, then dosed back to 1 ppm, then rechecked in 24 hours, I bet that ammonia w be moving down or zero (which is proof surfaces are ready)
Todays bottle bac makes tanks ready fast, way faster than 2 weeks which is how everyone is pulling off those fish-in cycles without loss. I would bet fully your tank can pass a clean water test. A wastewater test is subject to all kinds of misreads, searches on APi accuracy shows. You could easily just leave the current water running a few more weeks for it to clear, but then we're into regular cycling and didnt need that $ purchase. Its ready due to the $ purchase bottle bac.
misreads for nitrite include: any use of Prime water prep. high levels of nitrate cross read as nitrite on api kits
nitrite is unharmful at all stages, and we can see from cycling charts by day 20 it will always comply with ammonia (on a clean water test) so thats why whatever it reads right now doesnt matter. Even though the directions say to watch out for elevated levels, you can't stall a cycle with either boosted nitrite or ammonia, you can proceed. The labels are wrong.
