Cycling Water Change?

[mblackburn]

My ammonia spiked and dropped back to zero, and my nitrites are spiked currently with nitrates rising. My LFS advised to do a 25-30% water change.

I thought you shouldn't change the water while it's cycling? I was going to wait for nitrites to go to zero and then do a water change to lower the nitrates.

Thoughts?

As long as you don't have any live stock let the cycle, cycle

Wait till nitrite is 0. Add ammonia source. If nitrite drops to 0 within a day or so, you are good to go. Do a water change and begin stocking

wait till nitrites are 0 and don't ever go to that LFS again
