high nitrites in fish in cycle

[FrolfAddict93]

My API reading are under .25 ammonia 3-5pp. Mirror and 15 pp. nitrate.

I missed a day of tests and had really high nitrite reading doing a 50% water change

Am I almost done with the cycle?

Sorry I'm not completely understanding your test results. A completed cycle will be consistent readings of 0 ammonia, 0 nitrites & some nitrates.

.25 ppm ammonia 3-5 ppm nitrite 15ppm nitrate

Then your primary bacteria aren't well enough established to keep up with the ammonia output of your fish. When they are, the ammonia will drop to zero.

Similarly, your secondary bacteria aren't well enough established to keep up with the nitrite output from the primary bacteria, hence the nitrites in your water. Once they grow enough bacteria to match nitrite output, then your nitrites will drop to zero.

Then you're cycled.

You need to do some BIG water changes to get the nitrites down since you are doing a fish IN cycle. I would do a 50%+ water change, wait an hour & do another 50%+ water change.
