So I have had a QT running for a few weeks now. I am using a DIY sponge filter which was in my sump for about 2 months before putting it in the QT. So I tested the water tonight and results: Nitrate 0.2 Salifert Nitrite 0 API Ammonia 0.25 API I guess I don't remember correctly but I thought once the Nitrates were showing the Ammonia would have been gone. Is this API test inaccuracy? Is this tank still in the first stages of cycling and the last? I am a bit confused. Any info here is greatly appreciated.
