So my 20 gal community fish tank has been having some trouble with cycling. Its currently on day 24. On DAY 14, the nitrite levels went up to 5 ppm and then has been at 10 ppm for 9 DAYS. I did a 50% water change today. Btw, I have been adding ammonia almost every day and the ammonia keeps dropping to 0. For a couple days I added to much and it was at 4 ppm. However, it dropped down to 0. Am I adding to much ammonia? Pleaseeeee helpppp I want to get my fish sooooonnnn. Should I wait a couple days to test the nitrite and not add any ammonia? Or will that just kill all the bacteria and then I'll need to start over?
