Fishless Cycle - High NO2 and NO3 low Ammonia
It's been 3 weeks of a fishless cycle: it's a heavy planted tank - small 10gallon. I'm using pressurized CO2. I seem to be stuck at the following figures:
I was hoping that the Nitrites would drop to 0ppm, which then I'd add some liquid Ammonia to 2ppm, and monitor it's breakdown to 0ppm to ensure the cylce is done, but the Nitrites aren't moving. Should I do a 50% water change? Too much Nitrates bad for plants too no?
