Why after 3 weeks of cycling a tank is there no sign of nitrite? I have tons of ammonia, and I do water changes everyday. But if there is no sign of nitrite, then wouldn't that mean there are no beneficial bacteria in my tank yet to break down the ammonia? 10 gallon tank, 12 fathead minnows, AquaClear 20 power filter, 1-3 gallon whisper filter, aerator, heater with temp hovering around 76 degrees Fahrenheit. Should I remove the carbon insert from the filter?
