The pH/KH are? Below pH ~6.5, the nitrification bugs' growth slows down.
Below ~pH 6.0 they may arrest, but not die.
Temperature plays a role as well.

If the KH/pH is too low, it may not go anywhere. I don't think that
Ca++/Mg++ are involved in these processes.
Be sure to shake the test kit reagent bottles very, very well.
Nitrite/nitrate kits are notorious for settling out and under-reporting.
