I am attempting a fishless cycle on a small, nano-planted tank that is getting stuck on extremely high levels of nitrite. The tank has been set up for about two weeks now.
I am not dosing ammonia. I have two nerite snails in the tank that are creating some waste, so I get my ammonia from that and they are controlling any algae that might happen. My ammonia levels are usually always around 0.25 ppm.
After a water change, the nitrite spikes within 24 hours and then the nitrate will spike about 24-48 hours after that. However, the nitrite is still at extremely high levels even after the nitrate spikes.
Is this a patience game, waiting for the good bacteria to build and catch up to the output of nitrites? I have heard to do a water change when the nitrates get too high, but I don't want to disrupt the nitrite level in possibly letting good bacteria to colonize.
Any help on this would be awesome!
