Stubborn nitrite won't go down.

Wait, just to be clear, you have 2.0 and not 20 parts per million nitrite, corrct? If you have 20ppm I would be seriously worrying about your filter bacteria dying. I believe nitrifying bacteria die off at 8ppm ammonia, so I can't imagine the lethal dosage for nitrite is much different.

Yes 2.0 and not 20 sorry typo

Ok that's fine. It's not fine but for the purposes of this thread it's fine. Any nitrates recently?

Yes i mentioned in my earlier post that i had nitrite spiked down to 0, had high bitrate and did a water change yesterday tested today and i have nitrite spike.

Ok, it seems like the nitrite-oxidising bacteria are starting to grow and just need time to establish. I expect today or tomorrow you'll have 0 nitrites and a number of nitrates again. Don't dose ammonia again until you see nitrates.

Neither are actually true.

Don't dose ammonia again until you see nitrates.

I have to wonder if you read a thread or just react to the most recent post. This tank is already producing nitrates.

I'm so confused beyond confused. Yesterday when I updated my thread said I have nitrite when I added ammonia, and the next day I had 0 ammonia and 0 nitrite. Today I added 2ppm to test the cycle again came back from work. I have 2.0 ppm nitrite again what's going on?* Is my tank cycled? Or the reason I'm seeing nitrite is because I'm testing the same day? Like let's say I added ammonia today and I woke up the second day I would see 0 ammonia and 9 nitrite but it eating the same day is that why I'm seeing nitrite?

I know this can get very frustrating. Most of the time once nitrites drop to zero we don't see them again. For some reason your nitrite eating bacteria is slow. It may be because you are not giving it a full 24 hours after adding the ammonia.

And what I'm thinking as well is I'm adding ammonia 2ppm as one drop. When I have fish ammonia will rise slowly and not 2ppm at once and I won't see nitrite.

Exactly right. they just add a tiny bit at a time and the bacteria is constantly cleaning it up before it has time to get high enough to register in our tests.

I have to wonder if you read the most recent posts or just the OPs. I meant until they see nitrates appear again.
