Hello, I recently had a spike in nitrites, and now have that under control. I am trying to stock my school of Mollies (I currently have 4) and would like to have 9 to 10. How long should I wait (being as I just got nitrites under control yesterday,) to add more Mollies? I plan to add 3 at a time, 3 more times.
If it were me, I would wait to get straight readings of 0 for ammonia and nitrites for a few days before adding fish (I waited 5 days), then I'd add 2-4 a week But, I'd keep up with water testings everyday until the tank is well established.
