I cycled the tank!

I added 8 tiger barbs and 2 convicts 3 days ago

did water test today and My nitrite is up!!!!!!!!!!!:


Is this normal?

Yes. You will get a mini cycle when you first add fish. This is because the bio-load increases, and the bacteria lags, it will eventually catch up, and everything will be fine. I'm pretty sure this happens in fish less cycled tanks...


Also, you should really only add 2-4 fish every week, to make sure only a little Ammonia is being produced.

I thought the point of cycling was so you can add your entire bio-load......

So im all set?

My ammonia is being processed , just my nitrite lagging

Woops sorry, I forgot that isn't the case with fish less cycling


Although, I think it will still lag with a fish less cycle

how did you cycle and what did you use?

If you did a complete fishless cycle, you should not have seen any nitrite or ammonia. How much ammonia were you adding in the end and how long was it taking for ammonia and nitrite to both be back to zero? In the mean time, do partial water changes to keep the nitrite (and ammonia if it shows up) as low as possible, preferrable under .25 ppm.
