I have had my 24q Nano Cube up and running for 3 weeks. Durring the first week I put only 9 lbs of LR so I got 10 more pounds a week later, which was 2 weeks ago. My tank has be cycling for the last 2 weeks with me adding water when it needs and my levels have not gone up at all. I took some water to the LFS 2 weeks ago and the said amonia and nitrite were at 0 ppm and nitrate was at 20ppm whihc is what i thought too but I don't believe the tank is cycled yet. So they told me to put in a chemical called Cycle. I put it in the same time i added more LR and now I have a ton of pods and my diatoms are almost totally gone, could my tank already be cycled?
