Mr. Limpet said:IMO you're cycled. 10g is pretty small, so between the plant (high growth rate), nutrifying bacteria and the questionable brown scale of the n03 test, chances are its not absolute 0, but maybe 5 -7ppm which sounds right to me.
Agreed. If ammo and no2 suddenly dropped to 0 that means cycle complete (good job!). I'd also agree and attribute the no3 drop to the plant and the (less than) pinpoint accuracy of the API test.
