NO2- = 0,8 MG HELP !!!

[dorota]

AFTER 7 HOURS THAT I CHANGED 20 % OF THE WATER I REALIZED THAT MY AMBI WAS SWIMMING NEAR THE SURFACE MORE THAN BEFORE, TESTS ARE:

NO2- 0,8
KH 6
GH 12
NH3 NH4 0

IT IS THE FIRST TIME THAT NO2- IS WRONG, WHAT SHOULD I DO ???

NO2 = nitrite.
Do some additional partial water changes.

The other tests are fine. You did not give pH, but it is not usually a problem.
