Is this normal?
I'm on my 12th day of fish in cycling, and today I finally got some nitrites going on. However, there is no ammonia. Is this normal?
Yesterday I had .25ppm ammonia, 0ppm nitrites. Today I have 0ppm ammonia, .25ppm nitrites. I did a 30% water change and now there's 0ppm nitrites, no ammonia. I'm really happy I finally got nitrites going, but is it normal to have 0 ammonia and some nitrite? It may be just today, so I'm not sure what's to come tomorrow.
