As the nitrite rises, the ammonia starts to drop back down to 0 ppm. Days 7 & 8 – Measure ammonia and nitrite. On the first measurement day (Day 2, 4, 5, 7 or 8) that BOTH ammonia and nitrite are both below 0.5 ppm (NH3-N or NO2-N) your tank is close to being cycled. Now start to measure ammonia and nitrite every day. When BOTH ammonia and nitrite are below 0.2 ppm (NH3-N or NO2-N), add another 2 ppm ammonia.

It is a fairly new tank it is about 2-3 weeks old. So we bought an API Liquid Test kit and the levels came out darker than the 8.0 ppm level on the card. We also tested the tap water we are using for the tank and our tap water was at about 1.0-1.5 ppm. Days 7 & 8 – Measure ammonia and nitrite.
