Stalled Cycle or Finished Cycle?
I'm having a difficult time understanding why my API Nitrate keeps reading 0ppm. I've been dosing 2ppm Ammonia, which dissipates to 0ppm in 12 hours. When I read my Nitrite level, it hover's around 1ppm and my Nitrate reads 0ppm. How is that possible? If the ammonia is being converted to Nitrite, shouldn't:
1) the Nitrite level be much higher than 1ppm if I have no Nitrate?
2) the Nitrate kit is not correct. My steps for testing Nitrate is: 10 drops of bottle 1 -> invert test tube a few times -> shake bottle 2 vigorously for 30 sec -> 10 drops of bottle 2 into test tube -> shake vigorously for 1 min -> wait 5 mins and compare color by placing the test tube directly on the white area on the color card.
I've also been testing Nitrate using the Salifert Nitrate Kit and it reads ~50ppm or higher. With that in mind, I think the API kit is not working correctly.
Note: The Nitrite level has never reached 0ppm since I've been dosing ammonia to 2ppm daily. I'm going to stop dosing ammonia for 24 hours and see if the Nitrite zeroes out. If it does, I have a cycled tank?
