Welcome to the forum.
There are no 'accepted' peak levels. What you would like to see is that ammonia level goes up, then as it comes down the nitrites rise, as the nitrites decline the nitrates rise. Ultimately, yo would like to see the ammonia and nitrites go to zero as the nitrates peak. A water change, followed by the addition of a clean up crew should foolow.
How long does that usely take?Ive had my tank cycleing about 2.5 weeks.The ammonia is higher tonight than 4 days ago.Will it start down soon?And do nitrats have to be zero to put fish in?
