I've recently made the switch to the NP Suite of products and am experiencing the same 0.0 ppm (inorganic) Nitrate results using my trusty Hanna Nitrate HR kit.
Before the switch, I was using NeoNitro and NeoPhos to try to keep those numbers stable, but I see now that I was chasing numbers by doing that. My Nitrate target range at the time was 5.0 - 12.0 ppm. Two months ago, my Nitrate spiked 3 points to 12.7 ppm (the highest it had been in over a year). After 2 weeks of Elimi-NP, my Nitrates are pegged at 0.0. Even using Plus-NP and dosing NeoNitro (again) hasn't made Nitrate budge.
I think I just need to keep using NP-Bacto-Balance to keep the Phosphate levels in range and stop stressing about my inorganic Nitrate readings (even if they are zero).
@Court_Appointed_Hypeman, now that it has been another 6 months, are you still dosing Ammonium Chloride or NeoNitro or have things changed for your tank since then?
