everybody's tanks are different...i cant tell how long it will take for your nitrite to show up, but i would try lowering the ammonia you are adding...maybe 5 or 6 drops and see if that has any effects(veterans correct me if i'm wrong

)

o...and next time your going to be near a LFS, have them test your water and compare their readings to your's...just to see if your kit is correct
