Tank cycling starting?

Hi Iíve previously posted about very high ammonia level in my 10 g tank, and now ammonia is between .25 and 5.0. It looks like the nitrite level is slowly starting to change and is about .25. Could this mean my tank may be starting first part of nitrogen cycle? Iíve never had nitrites in tank before. Itís been over a month or 6 weeks since ammonia first spiked. Thanks 😊 Karen

Seeing nitrite is a sign your ammonia to nitrite bacteria are establishing. Any nitrate yet?

Nope no nitrate yet. How much nitrite is safe? Nitrate? Thanks Karen

As per my post #3 ammonia + nitrite no higher than 0.5ppm combined.

https://www.aquariumadvice.com/forum...os-379434.html

If you have 0.25 ammonia and 0.25 nitrite let it be. 0.5 ammonia and 0.25 nitrite change 1/3 of the water.

How often have you had to change water to keep your ammonia to these levels?

Keep doing what you are doing. Now you are seeing nitrite you need to keep an eye on that too. 0.25 ammonia and 0.25 nitrite, thats fine (0.5ppm combined).

Something is going right. Cycling can seem like a long process. Just curious, what filter are you using?
