Explain fishless cycle stall
I have heard that while doing a fishless cycle and your nitrites fail to come down, your cycle may have stalled and doing a 50% water change can get it going again.
Can someone explain this to me? From what I know about the nitrogen cycle, I just don't understand how the cycle can stall and why removing a big chunk of your nitrites with the water change restarts the cycle. Sounds to me like ammonia was overdosed causing a huge spike in the nitrites. Then the water change brings the levels back down to a level that you can now read and then continues coming down thus giving the illusion that the cycle was stalled and restarted. If you didn't do the water change the nitrites would have come down sooner or later and it wasn't stalled at all.
By tinkering with the cycle, don't you take a risk of not having a stable bacteria colony to handle a spike in ammonia. Shouldn't you let the nitrites come down naturally?
