Hi everyone, I just got into this hobby about 20 days ago. I have a 55 gallon high and a 10 gallon. Only 2 fish waiting for the cycle to complete. Quick question on my 55g I have had ammonia, nitrite, and nitrate. Saturday I had a 0.50
ppm ammonia, 0.25
ppm nitrite, and 5.0
ppm. Today I did a 45% water change and I have 0.25 ammonia, 0 nitrite, and 5.0 nitrate. What exactly does this mean? Is the cycle over?
