Yeah they seem to have been a bit lower the last couple of days, is that a sign it might be done soon?
Probably 3-4 more days. The Nitrite to Nitrate bacteria grow slower than the ammonia to Nitrite bacteria and they get a later start.
Is this a fishy or fishless cycle? I assuming fishless from the charts.
how much are you taking the ammonia back up to? looks close to being done.
